+Contract++
+
+Contract Programming Library for C++
+
+DESCRIPTION
+
+C++ Contract Programming (a.k.a. Design by Contract or DbC).
+All Eiffel features supported: subcontracting, postcondition old and result
+values, optional contract compilation, customizable action on assertion
+failure, block invariants, loop variants, etc.
+Plus virtual specifiers, concept checking, named parameters.
+See: http://contractpp.sourceforge.net
+
+FEATURES
+
+* Support for preconditions, postconditions, class invariants, block
+  invariants, and loop variants.
+* Subcontract derived classes (with support for pure virtual functions and
+  multiple inheritance).
+* Access expression old values and function return value in postconditions.
+* Optional compilation and checking of preconditions, postconditions, class
+  invariants, block invariants, and loop variants.
+* Customizable actions on contract assertion failure (terminate by default but
+  it can throw, exit, etc).
+* Virtual specifiers.
+* Concept checking.
+* Named parameters.
+

+
+[section Advanced Topics]
+
+This section explains advanced usages of this library in programming contracts.
+See the __Grammar__ section for a complete guide on this library syntax.
+
+[section Commas and Leading Symbols in Macros]
+
+C++ macros cannot correctly parse a macro parameter if it contains a comma `,` that is not wrapped within round parenthesis `()` (because the preprocessor interprets such a comma as separation between two distinct macro parameters instead that as part of one single macro parameter, see also __Boost_Utility_IdentityType__).
+Furthermore, syntactic elements specified to this library macros cannot start with a non-alphanumeric symbol (`-1`, `1.23`, `"abc"`, `::`, etc).
+[footnote
+Note that for the preprocessor a number with decimal period `1.23`, `0.12`, `.34` is considered a symbol (because its concatenation will not result in a valid macro identifier).
+]
+For example, the parameter type `::std::pair<OtherKey, OtherT> const&` cannot be passed to this library for two reasons: It starts with the non-alphanumeric symbol `::` and it contains the comma `OtherKey, OtherT` which is not wrapped by round parenthesis.
+
+The __Boost_Utility_IdentityType__ macro `BOOST_IDENTITY_TYPE` can be used as usual to overcome this issue.
+However, using the `BOOST_IDENTITY_TYPE` macro presents two limitations: It makes the syntax of this library macros more cumbersome and, more importantly, it does not allow C++ to automatically deduce function template parameters (see __Boost_Utility_IdentityType__ for more information).
+Therefore, the syntax of this library provides an alternative to `BOOST_IDENTITY_TYPE` to handle commas and leading symbols within macro parameters:
+
+# Commas and leading symbols can be used freely within elements of the syntax that already require wrapping parenthesis (e.g., non-fundamental parameter types `(::std::pair<OtherKey, OtherT> const&)`).
+# Extra parenthesis can always be used to wrap elements of the syntax that might contain commas and leading symbols (e.g, the base class type `public (::sizeable<Key, T>)`).
+# Extra parenthesis can always be used to wrap value expressions so they can contain commas and leading symbols (e.g., a class invariants assertion `(::sizeable<Key, T>::max_size >= size()`).
+
+For example (see also [file example/contracts macro_commas_symbols_integral_map.cpp]):
+
+[import ../example/contracts/macro_commas_symbols_integral_map.cpp]
+[macro_commas_symbols_integral_map]
+
+(Concepts and other advanced constructs used in this example are explained in the rest of this section and in later sections of this documentation.)
+
+All these extra wrapping parenthesis are optional when there is no unwrapped comma and no leading symbol.
+Programmers could chose to always program the extra parenthesis for consistency but it is the authors' opinion that the syntax is harder to read with the extra parenthesis so it is recommended to use them only when strictly necessary.
+
+It is also recommended to avoid using commas and leading symbols whenever possible so to limit the cases when it is necessary to use the extra wrapping parenthesis.
+For example, in many cases the leading symbol `::` might not be necessary and leading symbols like `!` can be replaced by the alternative `not` keyword.
+Furthermore, in some cases `typedef` can be programmed just before class and function declarations to avoid passing types within multiple template parameters separated by commas.
+Declarations of class templates and function templates are the most common cases were commas cannot be avoided and extra wrapping parenthesis are necessarily used.
+
+[warning
+Preconditions, postconditions, and class invariants composed of one single assertion that needs to be wrapped within extra parenthesis need to use double parenthesis (this should be a relatively rare case).
+[footnote
+*Rationale.*
+This limitation is introduced by the need to support also the sequence syntax for preprocessor without variadic macros (see the __No_Variadic_Macros__ section).
+]
+This is the case in the above example for `precondition( ((!full())) )` (but note that these extra parenthesis could have been avoided all together simply using `not` instead of `!` as in the more readable `precondition( not full() )`).
+]
+
+[endsect]
+
+[section Static Assertions]
+
+This library allows to use [@http://en.wikipedia.org/wiki/C%2B%2B11#Static_assertions /static assertions/] to program preconditions, postconditions, class invariants, and block invariants so that they are checked at compile-time instead of at run-time.
+The __CXX11__ syntax is used (but __Boost_MPL__ `BOOST_MPL_ASSERT_MSG` is used to implement static assertions so no __CXX11__ feature is required):
+
+    static_assert(``/constant-boolean-condition/``, ``/constant-string-literal/``)
+
+For example (see also [file example/contracts static_assertion_memcopy.cpp]):
+
+[import ../example/contracts/static_assertion_memcopy.cpp]
+[static_assertion_memcopy]
+
+Static assertions are always checked at compile-time (regardless of them appearing in preconditions, postconditions, etc).
+However, static assertions can be selectively disabled depending on where they are specified using [macroref CONTRACT_CONFIG_NO_PRECONDITIONS], [macroref CONTRACT_CONFIG_NO_POSTCONDITIONS], etc so it is still important to logically associate them with preconditions, postconditions, etc.
+
+The string message passed as the second parameter of `static_assert` is ignored by the current implementation of this library (but it could be used by future revisions of this library that take advantage of __CXX11__ features).
+It is recommended to always specify meaningful messages for static assertions to increase the readability and documentation of contracts.
+Similarly, it might be useful to put a short code comment following each assertions (`// pointer not null`, etc) to increase contract readability and documentation.
+[footnote
+*Rationale.*
+__Eiffel__ supports /assertion labeling/ to further documenting assertions.
+However, when designing this library for C++, the authors judged that it is sufficient to add a short code comment after each assertion to achieve a similar effect.
+]
+
+In case of a static assertion failure, this library will generated a compile-time error containing text similar to the following:
+
+[pre
+static_assertion_memcopy.cpp:18 ... ERROR_statically_checked_precondition_number_1_failed_at_line_18 ...
+]
+
+This message is similar to the run-time assertion errors generated by this library, note how it contains all the information to uniquely identify the assertion that failed.
+
+[endsect]
+
+[section Constant Assertions]
+
+As explained in the __Constant_Correctness__ section, contract assertions shall not change the state of the program because contracts are only supposed to check (and not alter) the state of the program.
+This library automatically makes member functions, function parameters, function result, and old values constant so the compiler will correctly generate an error if assertions mistakenly try to change the object, the function parameters, the function result, or the old values (this should be sufficient in most cases when programming contracts).
+
+[important
+This library cannot automatically make constant other variables that might be accessible by the contract assertions (e.g., global and static variables).
+[footnote
+*Rationale.*
+The library needs to know at least the variable name in order to make it constant.
+There is no way for this library to know the name of a global variable that is implicitly accessible from the contract assertion scope so such a variable cannot be automatically made constant.
+Non-static data members are automatically made constant by making constant the member function that checks the contract, but that does not apply to static data members.
+Not even __CXX11__ lambda implicit captures could be used in this context because they make variables constant only when captured by value and that introduces a __CopyConstructible__ requirement of the captured variable types.
+]
+]
+
+This library provides /constant assertions/ that can be used by programmers to explicitly make constant the variables used by the asserted condition:
+
+    const( ``/variable1/``, ``/variable2/``, ...) ``/boolean-expression-using-variable1-variable2-.../``
+
+The following example calculates the next even and odd numbers that are stored (for some reason) in a global variable and static data member respectively (see also [file example/contracts const_assertion_number.cpp]):
+
+[import ../example/contracts/const_assertion_number.cpp]
+[const_assertion_number]
+
+Note know the postconditions use constant assertions to force the `even` and `odd` variables to be constant within each boolean expression that evaluates the assertion.
+If for example the assignment operator `=` were mistakenly used instead of the equality operator `==` in the above postconditions, the compiler would correctly generate an error.
+
+[endsect]
+
+[section Select Assertions]
+
+In the __Tutorial__ section we have used the ternary operator `:?` to program assertions that are guarded by a boolean condition:
+
+    old_found ? true : std::find(begin(), end(), id) != end(),
+    old_found ? true : size() == old_size + 1
+
+However, in cases like this one when the same boolean condition guards multiple assertions, it might be more efficient to evaluate the guard condition only once using one /select assertion/ instead of multiple ternary operators `:?`.
+In addition, some programmers might find the select assertion syntax more readable than the ternary operator `:?`.
+For example, the above guarded assertions could have been programmed using select assertions as:
+
+    if(not old_found) ( // Guard condition evaluated only once.
+        std::find(begin(), end(), id) != end(),
+        size() == old_size + 1
+    )
+
+Select assertion allow to specify an optional else-block:
+
+    if(``/boolean-condition/``) (   // Round parenthesis `()`.
+        ...                   // Comma-separated assertions.
+    ) else (                  // Else optional as usual.
+        ...                   // Comma-separated assertions.
+    )
+
+Note that round parenthesis `( ... )` are used to program the then-block and else-block instead of the usual C++ curly parenthesis `{ ... }`:
+Select assertions can be nested into one another (the [macroref CONTRACT_LIMIT_NESTED_SELECT_ASSERTIONS] macro specifies the maximum nesting level for select assertions).
+
+For example, consider the postconditions of the following function which calculates the factorial of a natural number (see also [file example/contracts select_assertion_factorial.cpp]):
+
+[import ../example/contracts/select_assertion_factorial.cpp]
+[select_assertion_factorial]
+
+Using the same syntax used for constant assertions, it is possible to force all variables (global, static, etc) used to evaluate the if-condition of the select assertion to be constant (see also [file example/contracts const_select_assertion_factorial.cpp]):
+
+[import ../example/contracts/const_select_assertion_factorial.cpp]
+[const_select_assertion_factorial]
+
+[endsect]
+
+[section Assertion Statements]
+
+Only assertions can be programmed within the contracts while normal C++ statements are not allowed.
+This is keeps contracts simple making programming errors within the contracts less likely and therefore increasing the probably that error-free contracts can properly check the correctness of the implementation.
+
+However, `using` directives, `namespace` aliases, and `typedef` statements are allowed within the contracts because they only affect compilation (not altering the state of the program at run-time) and they can be used to write more readable contracts (for example, shortening namespaces within contract assertions).
+When used, these statements have affect only locally within the preconditions, postconditions, class invariants, etc where they appear.
+[footnote
+Assertion statements might be especially useful because contracts appear with the class and function declarations usually in header files where `using` directives and `namespace` aliases should only be used with extreme care and, for example, at local scope as assertion statements allow to do.
+]
+
+For example (see also [file example/contracts assertion_statement_ialloc.cpp]):
+
+[import ../example/contracts/assertion_statement_ialloc.cpp]
+[assertion_statement_ialloc]
+
+These statements follow their usual C++ syntax but they are terminated with a comma `,` instead of a semicolon `;`.
+(The `BOOST_IDENTITY_TYPE` macro can be used to wrap eventual commas within the `typedef` statement.)
+
+[endsect]
+
+[section Assertion Requirements]
+
+In general, programming contract assertions can introduce a new set of requirements on the types used by the program.
+Some of these type requirements might be necessary only to program the assertions and they might not be required by the implementation itself.
+In such cases, if the code is compiled with contracts disabled ([macroref CONTRACT_CONFIG_NO_PRECONDITIONS], etc), the program might compile but it might no longer compile when contracts are enabled because some of the types do not provide all the operations necessary to check the contract assertions.
+
+# More in general, in some cases it might be acceptable or even desirable to cause a compile-time error when a program uses types that do not provide all the operations needed to check the contracts (because it is not possible to fully check the correctness of the program).
+In these cases, programmers specify contract assertions as we have seen so far (and maybe even use concepts to explicitly specify the contract type requirements, see the __Concepts__ section).
+# However, in other cases it might be desirable that adding contracts to a program does not change its type requirements and that assertions are simply not checked when the types do not provide all the operations necessary to evaluate the asserted conditions.
+In these cases, programmers can use /assertion requirements/ to disable compilation and run-time checking of specific assertions:
+[footnote
+*Rationale.*
+The assertion requirement syntax takes a constant boolean expression instead of a nullary boolean meta-function because the authors have found no reason to use a meta-function in this context.
+Furthermore, constant boolean expressions can be manipulated via the usual operators `not`, `and`, etc, therefore more naturally than boolean meta-functions which need to use `boost::mpl::not_`, `boost::mpl::and_`, etc instead.
+]
+
+    ``/assertion/``, requires ``/constant-boolean-expression/``
+
+(The constant boolean expression of an assertion requirement can be wrapped within round parenthesis `()` if it contains unwrapped commas.)
+
+Let's consider the STL `std::vector<T>` class template.
+This template normally does not require the value type `T` to be __EqualityComparable__ (i.e., to have an equality operator `==`), it only requires `T` to be __CopyConstructible__ (i.e., to have a copy constructor).
+However, in order to check the following `std::vector<T>::push_back` postcondition:
+
+    back() == value // Compiler error if not `EqualityComparable<T>`.
+
+The type `T` must to be __EqualityComparable__.
+Therefore, the __EqualityComparable__ requirement on `T` is introduced only by the contract assertions and it is not required by the `std::vector<T>` implementation.
+
+In some cases, programmers might want compilation to fail when `T` is not __EqualityComparable__ because in these cases it is not possible to fully check the `std::vector<T>` contract and therefore its correctness (in these cases programmers do not specify assertion requirements and let the compilation fail, or even better programmers can explicitly specify the assertion type requirements using concepts which will also fail compilation but hopefully with more informative error messages, see the __Concepts__ section).
+
+However, in other cases programmers might want to use the contracted version of `std::vector<T>` exactly as they use the non-contracted version of the template and therefore without failing compilation if `T` is not __EqualityComparable__.
+This can be achieved specifying assertion requirements for the `std::vector<T>::push_back` postcondition:
+
+    back() == value, requires boost::has_equal_to<T>::value // No error if not `EqualityComparable<T>`.
+
+This postcondition will be checked only when `T` is __EqualityComparable__, otherwise the postcondition will be ignored otherwise causing no compilation error.
+    
+For example (see also [file example/contracts assertion_requirements_push_back.cpp]):
+[footnote
+Future revisions of this library might provide wrappers that program contracts for the STL in appropriate header files =contract/std/vector.hpp=, =contract/std/algorithm.hpp=, etc (see also [@http://www.sgi.com/tech/stl/ SGI STL] and [@http://sourceforge.net/apps/trac/contractpp/ticket/47 Ticket 47]).
+However, given that STL implementations are usually considered to be ["correct], it is not clear if STL class invariants and postconditions would add any value, maybe programmers would only find STL preconditions useful.
+]
+
+[import ../example/contracts/assertion_requirements_push_back.cpp]
+[assertion_requirements_push_back]
+[assertion_requirements_push_back_call]
+
+The `i.push_back(123)` call will check the postcondition `back() == value` because `int` is __EqualityComparable__ and the assertion requirement `boost::has_equal_to<int>::value` is true.
+However, the `n.push_back(num(123))` call will not check, and in fact not even compile, the postconditions `back() == value` because `num` is not __EqualityComparable__ and the assertion requirement `boost::has_equal_to<num>::value` is false.
+[footnote
+Assertion requirements where first introduced by this library and they are not supported by __N1962__, __D__, or __Eiffel__ (even if they all allow to write contracts for templates).
+Based on the authors' experience, assertion requirements are necessary for a language that make extensive use of templates like C++.
+Furthermore, C++ does not automatically define equality operators `==` while it automatically defines copy constructors and that make the use of the assertion requirements for __EqualityComparable__ a rather common practise (in __Eiffel__ instead types can be both copied and compared for equality by default).
+It has been argued that it is not possible to check a program for correctness if types that are copyable cannot also be compared for equality and the authors experience with programming contracts confirms such an argument.
+]
+
+The __Boost_TypeTraits__ library provides a set of meta-functions that are very useful to program assertion requirements.
+[footnote
+As of __Boost__ 1.50, `boost::has_equal_to` and similar traits always return true for an STL container even if the value type of the container does not have an operator `==`.
+This is arguably a defect of the STL that always defines an operator `==` for its containers even when a container template is instantiated with a value type that has no operator `==`, in which case the container operator `==` will produce a compiler error (the STL should instead use __SFINAE__ to disable the declaration of the container operator `==` when the value type has no operator `==`).
+Future versions of __Boost_TypeTraits__ will probably specialize `boost::has_equal_to` and similar traits to work around this behaviour of the STL.
+In the meanwhile, programmers can specialize these traits themselves if needed:
+``
+// Header: std_has_equal_to.hpp
+#include <boost/type_traits/has_equal_to.hpp>
+#include <boost/type_traits/is_convertible.hpp>
+#include <boost/mpl/and.hpp>
+#include <vector>
+
+// STL defines `operator==` only between two identical containers (same value
+// type, allocator, etc) and returning a type convertible to `bool`.
+
+namespace boost {
+
+// Specializations for `std::vector`.
+
+template< typename T, class Alloc >
+struct has_equal_to < std::vector<T, Alloc>, std::vector<T, Alloc> > :
+    has_equal_to<T, T, bool>
+{};
+
+template< typename T, class Alloc, typename Ret >
+struct has_equal_to < std::vector<T, Alloc>, std::vector<T, Alloc>, Ret > :
+    mpl::and_<
+          has_equal_to<T, T, bool>
+        , is_convertible<Ret, bool>
+    >
+{};
+
+// ... specialize `has_equal_to` for more STL containers.
+
+} // namespace
+``
+]
+However, C++ does not allow to inspect every trait of a type so there might be some assertion requirements that unfortunately cannot be programmed within the language.
+
+Another interesting use of assertion requirements is to model assertion computational complexity.
+In some cases, checking assertions can be as computationally expensive as executing the function body or even more.
+While preconditions, postconditions, etc can be disabled in groups at compile-time to improve performance (using [macroref CONTRACT_CONFIG_NO_PRECONDITIONS], [macroref CONTRACT_CONFIG_NO_POSTCONDITIONS], etc), it is also useful to be able to disable only specific assertions that are very computationally expensive while keeping all other preconditions, postconditions, etc enabled.
+For example (see also [file example/contracts assertion_complexity_factorial.cpp]):
+
+[import ../example/contracts/assertion_complexity_factorial.cpp]
+[assertion_complexity_factorial]
+
+In this case the postcondition `result = n * factorial(n - 1)` has factorial computation complexity and it is compiled and checked at run-time only if the macro `COMPLEXITY_MAX` is defined to be `O_FACTN` or greater.
+Similarly, macros like `O_SMALLER_BODY`, `O_BODY`, and `O_GREATER_BODY` could have been defined to express computational complexity in relative terms with respect to the body computational complexity (see the __Examples__ section).
+[footnote
+__N1866__, an earlier version of __N1962__, introduced the notion of /importance ordering/ that could be used to selectively disable assertions that where too expensive computationally.
+Important ordering was then dropped by __N1962__.
+Among other things, assertion requirements can be used to achieve the importance ordering functionality.
+]
+
+Assertion requirements can be used with assertions, constant assertions, and static assertions but they cannot be used with assertion statements and with the if-then-else statements of select assertions (however, if select assertions are programmed using the ternary operator `:?` then assertion requirements will disable the entire ternary operator `:?` expression including its if-condition).
+
+[endsect]
+
+[section Old-Of Requirements]
+
+Assertion requirements can be specified also for postconditions that use old values.
+However, old values have the additional requirement that the type of the expression passed to the [macroref CONTRACT_OLDOF] macro must be __ConstantCopyConstructible__.
+If such a requirement is not met:
+
+# Either, programmers want the compiler to error because the postconditions using the old value cannot be evaluated (in which case programmers will not specify assertion requirements and they might explicitly specify type requirements using concepts so to get more informative error messages, see the __Concepts__ section).
+# Or, programmers want the old value declaration that uses the [macroref CONTRACT_OLDOF] macro to have no effect (because the old value cannot be copied) and the postconditions using such an old value to not be evaluated.
+
+Unfortunately, C++ cannot automatically detect if a type has a copy constructor therefore a special trait [classref contract::has_oldof] had to be introduced to support this second case.
+The `contract::has_oldof<T>` trait is a unary boolean meta-function which is `boost::mpl::true_` by default for any type `T` and it must be specialized by programmers for types which old values cannot be copied.
+
+For example, consider the following increment function (see also [file example/contracts has_oldof_inc.cpp]):
+
+[import ../example/contracts/has_oldof_inc.cpp]
+[has_oldof_inc]
+[has_oldof_inc_call]
+
+In this example, the `num` type is non-copyable so the `contract::has_oldof<num>` specialization inherits from `boost::mpl::false_`.
+As a consequence, the call `inc(n, m)` will automatically skip the old value declaration:
+
+    auto old_value = CONTRACT_OLDOF value
+
+The following postcondition will also be skipped because its assertion requirement lists `contract::has_oldof<T>` (where `T` is indeed the type of `value` passed to the [macroref CONTRACT_OLDOF] macro):
+
+    value == old_value + offset, requires contract::has_oldof<T>::value && ...
+
+Note how this postcondition actually requires the type `T` to have an old value, a plus operator `+`, and an equality operator `==` thus all of these requirements are programmed in the assertion requirements.
+
+Finally, return value declarations are never skipped so there is no `has_result` trait.
+[footnote
+*Rationale.*
+The result type needs to be copyable in order for the function itself to return a value so this library can always evaluate return value declarations.
+]
+
+[endsect]
+
+[section Old and Result Value Copies]
+
+This library uses the class template [classref contract::copy] to copy old values and the result value for postconditions.
+    
+    namespace contract
+    {
+        template< typename T >
+        class copy
+        {
+            public: copy ( T const& object ) ;
+            public: T const& value ( void ) const ;
+        };
+    } // namespace
+
+The default implementation of the [classref contract::copy] class template requires that the type of the old value expression passed to the [macroref CONTRACT_OLDOF] macro and the result type are __ConstantCopyConstructible__ (i.e., these types provide a copy constructor that copies the object from a constant reference, the reference has to be constant so to ensure the constant-correctness of the copy operations that are executed within the contracts, see also the __Constant_Correctness__ section):
+
+    // `ConstantCopyConstructible<T>` (which implies `CopyConstructible<T>`):
+    T::T ( T const& source ) ;  // OK: constant-correct copy constructor.
+
+    // `CopyConstructible<T>` (but not `ConstantCopyConstructible<T>`):
+    T::T ( T& source ) ;        // Error, copy constructor is not constant-correct.
+
+Programmers can specialize the [classref contract::copy] class template to allow old value and result value copies even for types that are not __ConstantCopyConstructible__ (in this case it is the programmers' responsibility to make sure that the copy operations that they define are constant-correct, otherwise the contracts will no longer be constant-correct).
+[footnote
+Currently, it is not possible to force constant-correctness of the expression passed to the [macroref CONTRACT_OLDOF] macro.
+Future revisions of this library will support `CONTRACT_OLDOF const( ... ) ...` to allow to make constant all variables (including global, static, etc) used by old value expressions (see also [@http://sourceforge.net/apps/trac/contractpp/ticket/52 Ticket 52]).
+]
+
+In the following example the old and result value declarations use the specialization `contract::copy<num>` so it is possible to access the old and result value of variables of type `num` even if `num` is non-copyable (see also [file example/contracts copy_inc.cpp]):
+
+[import ../example/contracts/copy_inc.cpp]
+[copy_inc]
+[copy_inc_call]
+
+Both calls `inc(i, j)` and `inc(n, m)` check all postconditions.
+The first call copies the old and result values using `int`'s default copy constructor, the second call copies the old and result values using the copy operation implemented by the `contract::copy<num>` specialization.
+
+[endsect]
+
+[section Pure Virtual Functions]
+
+It is possible to program contracts for pure virtual functions.
+Pure virtual functions are specified with the usual `= 0;` symbol replacing the function definition just after the contract macros, for example (see also [file example/contracts pushable.hpp]):
+
+[import ../example/contracts/pushable.hpp]
+[pushable]
+
+Furthermore, using the [macroref CONTRACT_MEMBER_BODY] macro, a derived class can be programmed without using the [macroref CONTRACT_CLASS] and [macroref CONTRACT_FUNCTION] macros even when the base class has pure virtual functions (see also [file example/contracts default_subcontracting_base.cpp]):
+
+[import ../example/contracts/default_subcontracting_base.cpp]
+[default_subcontracting_base]
+
+This use of the [macroref CONTRACT_MEMBER_BODY] macro does not force programmers of derived classes to use the library macros [macroref CONTRACT_CLASS] and [macroref CONTRACT_FUNCTION] which would otherwise introduce the unusual library syntax in the derived class declaration.
+However, in this case the derived class is forced to inherit the base class invariants, preconditions, and postconditions exactly as they are without the possibility to truly subcontract the base class (which is instead possible when the [macroref CONTRACT_CLASS] and [macroref CONTRACT_FUNCTION] macros are used in declaring the derived class).
+[footnote
+*Rationale.*
+Older revisions of this library defined the macro `CONTRACT_MEMBER_BODY(class_type, function_name)` taking two parameters so this macro could not be used in declaring derived classes and the [macroref CONTRACT_CLASS] and [macroref CONTRACT_FUNCTION] macros where required when programming a class inheriting from a base class with contracts.
+However, the authors prefer to leave the choice of programming full contracts for derived classes to the derived class programmers because of the unusual declaration syntax introduced by this library might not be necessary when derived classes do not need to alter the base's class contract.
+]
+Correctly, the derived class can never avoid checking the base class contracts neither when declared using the [macroref CONTRACT_CLASS] and [macroref CONTRACT_FUNCTION] macros, nor when declared using the [macroref CONTRACT_MEMBER_BODY] macro.
+
+[endsect]
+
+[section Subcontracting Preconditions]
+
+While subcontracting is theoretically sound and justified by the __substitution_principle__, in practise subcontracted preconditions might be confusing for programmers because of the implications of evaluating overriding preconditions in __logic_or__ with overridden preconditions (this is not the case for subcontracted postconditions and class invariants which usually behave as programmers expect because they are evaluated in __logic_and__).
+
+For example, consider the following base class `integer` which holds an integral value and its derived class `natural` which holds a natural (i.e., non-negative integer) value (see also [file example/contracts subcontract_pre_natural_failure.cpp]):
+
+[import ../example/contracts/subcontract_pre_natural_failure.cpp]
+[subcontract_pre_natural_failure]
+
+From reading the contracts we conclude that:
+
+* `integer::get` returns the latest value set (as specified by `integer::set` postconditions).
+* There is no constraint on the integer value that is passed to `integer::set` (because `integer::set` has no precondition).
+* `natural::get` always returns a non-negative value (as specified by the `natural` class invariants).
+* Only non-negative values can be passed to `natural::set` (as specified by `natural::set` preconditions).
+
+This last conclusion is incorrect!
+Negative values can be passed to `natural::set` because they can be passed to its base virtual function `integral::set` (preconditions cannot only be weakened).
+The complete set of `natural::set` preconditions is given by its base virtual function `integer::set` preconditions (which are always `true` because they are not specified) evaluated in __logic_or__ with the preconditions explicitly specified by `natural::set` (i.e., `value >= 0`):
+
+    (true) or (value >= 0)
+
+Obviously, this always evaluates to `true` regardless of `value` being non-negative.
+This is correct in accordance with the __substitution_principle__ for which `natural::set` can be called in any context where `integer::set` is called because `natural` inherits from `integer`.
+Given that `integer::set` can be called regardless of `value` being non-negative (because it has no precondition) there is no precondition that we can later specify for `natural::set` that will change that and in fact `natural::set` can also be called with negative values without failing its subcontracted preconditions.
+For example, the call:
+
+[subcontract_pre_natural_failure_call]
+
+Fails the class invariants checked while exiting `natural::set`:
+
+[pre
+class invariant (on exit) number 1 "get() >= 0" failed: file "natural_subcontractpre.cpp", line 30
+]
+
+Ideally, this call would have failed much earlier at `natural::set` preconditions (in fact, the `natural::set` body is executed with the logically invalid negative value `-123` which could in general lead to catastrophic errors and mysterious bugs).
+
+The issue here is in the design.
+A natural number is not an integer number because while it is valid to use an integer number in a context where it is assigned to a negative number, it is not valid to use a natural number in such a context so a natural number should not inherit from an integer number.
+Inheritance models the [@http://en.wikipedia.org/wiki/Is-a /is-a/] relationship which should not be used in this case as the contracts and the __substitution_principle__ are telling us.
+
+[note
+Note that if a virtual member function has no preconditions, it means that it is always valid to call it, and (in accordance with the __substitution_principle__) this semantic cannot be changed by the contracts of any overriding function no matter what preconditions we specify for it.
+Similarly, if an overriding member function has no preconditions, it means that is is always valid to call it regardless of possible preconditions specified by any function that it overrides.
+]
+
+An overriding function can specify `precondition( false )` if it wants to keep the same preconditions of the functions that is overriding.
+A pure virtual function can specify `precondition( false )` to indicate that overriding functions will specify preconditions (this only makes sense for pure virtual functions because a function with `precondition( false )` can never be called successfully unless it is overridden and its preconditions are weakened, that might be acceptable for pure virtual because they must always be overridden).
+
+If programmers find subcontracted preconditions confusing, this library allows to forbid them by defining the configuration macro [macroref CONTRACT_CONFIG_DO_NOT_SUBCONTRACT_PRECONDITIONS].
+When this macro if defined, the library will generate a compile-time error if a derived class tries to override preconditions of member functions of any of its base classes (this is also the subcontracting behaviour specified by __N1962__).
+However, note that in case of multiple-inheritance preconditions from the overridden function from all bases classes will always be checked in __logic_or__ with each other so preconditions from a base class could still be weaken by the preconditions of another base class even when the [macroref CONTRACT_CONFIG_DO_NOT_SUBCONTRACT_PRECONDITIONS] macro is defined.
+By default the [macroref CONTRACT_CONFIG_DO_NOT_SUBCONTRACT_PRECONDITIONS] macro is not defined and this library allows to override preconditions (as specified by for __Eiffel__ by __Meyer97__ and in accordance with the __substitution_principle__).
+
+Another difference between subcontracted preconditions and subcontracted postconditions or class invariants is that subcontracted preconditions will always report a failure of the overridden preconditions.
+For example, consider a set of base classes [^b['N]] and a derived class `d`:
+    
+    CONTRACT_CLASS(
+        struct (a)
+    ) {
+        ... // No member function `f`.
+    };
+
+    CONTRACT_CLASS(
+        struct (b``/N/``)
+    ) {
+        CONTRACT_CLASS_INVARIANT( ... )
+
+        CONTRACT_FUNCTION(
+            public virtual void (f) ( void ) // Overridden function.
+                precondition( ... )
+                postcondition( ... )
+        ) {}
+
+        ...
+    };
+    
+    CONTRACT_CLASS(
+        struct (c)
+    ) {
+        ... // No member function `f`.
+    };
+
+    CONTRACT_CLASS(
+        struct (d) extends( b1, a, b2, c, b3 )
+    ) {
+        CONTRACT_CLASS_INVARIANT( ... )
+        
+        CONTRACT_FUNCTION(
+            public virtual void (f) ( void ) // Overriding function.
+                precondition( ... )
+                postcondition( ... )
+        ) {}
+        
+        ...
+    };
+
+When `d::f` is called, its subcontracted class invariants, postconditions, and preconditions are evaluated using the following expressions (the base classes `a` and `c` do not declare a virtual function `f` so they are automatically excluded from `d::f` subcontracting):
+
+    b1::``/class-invariants/``  and b2::``/class-invariants/``  and b3::``/class-invariants/``  and d::``/class-invariants/``  // `d::f` subcontracted class invariants.
+    b1::f::``/postconditions/`` and b2::f::``/postconditions/`` and b3::f::``/postconditions/`` and d::f::``/postconditions/`` // `d::f` subcontracted postconditions.
+    b1::f::``/preconditions/``  or  b2::f::``/preconditions/``  or  b3::f::``/preconditions/``  or  d::f::``/preconditions/``  // `d::f` subcontracted preconditions.
+
+When subcontracted class invariants or subcontracted postconditions fail, this library reports the first failed condition which can in general be in the base class contracts because they are checked first in the __logic_and__ chain (this can report a failure from any subcontracted class invariants [^b['N]::/class-invariants/] or [^d::/class-invariants/], and subcontracted postconditions [^b['N]::f::/postconditions/] or [^d::f::/postconditions/]).
+However, when subcontracted preconditions fail it means that all overridden preconditions as well as the overriding preconditions have failed (because subcontracted preconditions are evaluated in __logic_or__).
+In this case, this library will report the last evaluated failure which will always be in the overriding preconditions (always report a failure from [^d::f::/preconditions/]).
+If programmers want instead the library to report the failure from the first overridden precondition that failed, they can define the configuration macro [macroref CONTRACT_CONFIG_REPORT_BASE_PRECONDITION_FAILURE] (always report a failure from [^b1::f::/preconditions/]).
+
+[endsect]
+
+[section Static Member Functions]
+
+It is possible to program contracts for static member functions.
+Static member functions cannot access the object therefore their preconditions and postconditions also cannot access the object and they can only access other static members.
+This library allows to specify a subset of class invariants called /static class invariants/ which do not access the object and that are checked at entry and exit of every constructor, destructor, and member functions even if static.
+(Non-static class invariants are instead not checked at constructor entry, at destructor exit, and at entry and exit of static member functions because they require accessing the object, see also the __Contract_Programming_Overview__ section.)
+
+Static class invariants are empty (`void`) by default unless they are explicitly specified within the [macroref CONTRACT_CLASS_INVARIANT] macro using the following syntax:
+[footnote
+Static class invariants are not part of __N1962__ and they were first introduced by this library.
+]
+
+    static class( ``/assertion1/``, ``/assertion2/``, ... )
+
+For example (see also [file example/contracts static_contract_instance_counter.cpp]):
+
+[import ../example/contracts/static_contract_instance_counter.cpp]
+[static_contract_instance_counter]
+
+In this example there is only one static class invariant assertion `count() >= 0` and it is checked at entry and exit of every constructor, destructor, and member function including the static member function `count`.
+If the static member function `count` had preconditions or postconditions, they would not be able to access the object (i.e., preconditions and postconditions will also be executed in static context).
+
+[endsect]
+
+[section Volatile Member Functions]
+
+It is possible to program contracts for volatile member functions.
+Volatile member functions access the object as volatile therefore their preconditions and postconditions also access the object as volatile and can only access other volatile members.
+This library allows to specify a different set of class invariants called /volatile class invariants/ which can only access the object as volatile and that are checked at entry and exit of every volatile member function.
+(Constructors and destructors never access the object as volatile so volatile class invariants are not checked by constructors and destructors, see also the __Contract_Programming_Overview__ section.)
+
+Volatile class invariants are assumed to be the same as non-volatile class invariants unless they are explicitly specified within the [macroref CONTRACT_CLASS_INVARIANT] macro using the  following syntax:
+[footnote
+Volatile class invariants are not part of __N1962__ and they were first introduced by this library.
+It is not clear if there are real applications for volatile class invariants mainly because real applications of `volatile` itself are not clear in C++.
+One very interesting use of `volatile` has been to [@http://www.drdobbs.com/cpp/184403766 avoid race conditions] in concurrent programming (but contracts are not useful for such an application of `volatile`).
+]
+
+
+    volatile class( ``/assertion1/``, ``/assertion2/``, ... )
+
+In most cases, it will be necessary to explicitly specify volatile class invariants when using volatile member functions (unless volatile overloads are provided for every member function that is used by the non-volatile class invariants).
+
+For example (see also [file example/contracts volatile_contract_shared_instance.cpp]):
+
+[import ../example/contracts/volatile_contract_shared_instance.cpp]
+[volatile_contract_shared_instance]
+
+As usual, contracts are checked in constant-correct context therefore only `const volatile` members can be accessed from volatile class invariants, preconditions, and postconditions.
+
+[endsect]
+
+[section Operators]
+
+It is possible to program contracts for operators (both member function operators and free function operators).
+The operator name must be specified using the following syntax when passed to the [macroref CONTRACT_FUNCTION], [macroref CONTRACT_FREE_BODY], and [macroref CONTRACT_MEMBER_BODY] macros:
+
+    operator(``/symbol/``)(``/arbitrary-alphanumeric-name/``)
+
+The first parameter is the usual operator symbol (`==`, `+`, etc) the second parameter is an arbitrary but alphanumeric name (`equal`, `plus`, etc).
+The operator `new`, the operator `delete`, and implicit type conversion operators for fundamental types containing no symbol can also be specified simply as:
+
+    operator new
+    operator delete
+    operator ``/fundamental-type-without-symbols/``
+
+The comma operator must be specified as:
+[footnote
+*Rationale.*
+The comma operator cannot be specified using the comma symbol as in `operator(,)(my_comma_operator)` because the preprocessor uses commas to separate macro parameters so it is not possible to distinguish that from an implicit type conversion operator like `operator(std::vector<T, Allocator>)(std_vector)` (note that the operator name is arbitrary so it also cannot be used to distinguish these two cases).
+]
+
+    operator comma
+
+For example (see also [file example/contracts member_operator_string.cpp]):
+
+[import ../example/contracts/member_operator_string.cpp]
+[member_operator_string]
+
+The memory operators `new`, `delete`, `new[]`, and `delete[]` must always be specified `static` when they are programmed as member function operators.
+[footnote
+*Rationale.*
+C++ automatically promotes memory member operators to static members so the `static` keyword is optional for these member operators.
+However, this library cannot inspect the operator symbol using the preprocessor to check if the operator is a memory member operator or not because the symbol contains non-alphanumeric tokens (which cannot be concatenated by the preprocessor).
+Therefore, this library always requires memory member operators to be explicitly declared as static member functions.
+]
+
+Free function operators are programmed using the same syntax for the operator names.
+
+[endsect]
+
+[section Nested Classes]
+
+It is possible to program contracts for nested classes noting that:
+
+# The access level `public`, `protected`, or `private` must be specified for contracted members and therefore also for nested classes. 
+# The `_TPL` macros must be used within templates so the [macroref CONTRACT_CLASS_TPL] macro needs to be used when programming a class nested within a class template.
+
+For example (see also [file example/contracts nested_class_bitset.cpp] and the __Concepts__ section):
+
+[import ../example/contracts/nested_class_bitset.cpp]
+[nested_class_bitset]
+
+[endsect]
+
+[section Friends]
+
+It is possible to program contracts for friend classes and friend functions.
+Classes can be declared friends and later contracted using the [macroref CONTRACT_CLASS] macro as usual:
+
+    CONTRACT_CLASS( // Not even necessary to contract this class.
+        class (x)
+    ) {
+        CONTRACT_CLASS_INVARIANT( void )
+
+        friend class y ;
+
+        // ...
+    };
+    
+    CONTRACT_CLASS(
+        class (y)
+    ) {
+        CONTRACT_CLASS_INVARIANT( void )
+
+        // ...
+    };
+
+Friend functions that are declared and defined within the enclosing class use the `friend` keyword within the [macroref CONTRACT_FUNCTION] macro (note that the access level `public`, `protected`, or `private` is optional in this case because these friend functions are not member functions).
+Friend functions that are either forward declared friends or that are defined friends within the enclosing class, must use the [macroref CONTRACT_FREE_BODY] macro.
+For example (see also [file example/contracts friend_counter.cpp]):
+
+[import ../example/contracts/friend_counter.cpp]
+[friend_counter]
+
+The class enclosing the friend declarations might or might not be contracted.
+
+[endsect]
+
+[section Template Specializations]
+
+It is possible to program contracts for class template specializations.
+The generic class template might or might not be contracted (see also [file example/contracts template_specializations_vector.cpp]):
+
+[import ../example/contracts/template_specializations_vector.cpp]
+[template_specializations_vector]
+
+The template specialization types follow the class name as usual but they are wrapped within round parenthesis `( bool, Allocator )` instead than angular parenthesis `< bool, Allocator >` as in the following partial specialization:
+
+[template_specializations_vector_bool_allocator]
+
+The syntax `template( void )` must be used instead of `template< >` to indicate explicit specializations:
+
+[template_specializations_vector_bool]
+
+[endsect]
+
+[section Exception Specifications and Function-Try Blocks]
+
+It is possible to program exception specifications and function-try blocks for constructors, destructors, member functions, and free functions with contracts.
+Exception specifications are part of the function declarations therefore they are programmed within the contract macros but the special syntax `throw( void )` must be used instead of `throw( )` to specify that no exception is thrown:
+
+    throw( ``/exception-type1/``, ``/exception-type2/``, ... ) // As usual.
+    throw( void ) // Instead of `throw( )`.
+
+Function-try blocks are part of the function definition so they are normally programmed outside the contract macros.
+However, for constructors with member initializers, the member initializers must be programmed within the [macroref CONTRACT_CONSTRUCTOR] macro and therefore also the function-try blocks must be programmed within the macro using the following syntax:
+
+    try initialize( ``/initializer1/``, ``/initializer2/``, ... )
+    catch(``/exception-declaration1/``) ( ``/instruction1/``; ``/instruction2/``; ... )
+    catch(``/exception-declaration2/``) ( ``/instruction1/``; ``/instruction2/``; ... )
+    catch(...) ( ``/instruction1/``; ``/instruction2/``; ... )
+
+As usual, only one catch statement must be specified and the other catch statements are optional plus `catch(...)` can be used to catch all exceptions.
+Note however that round parenthesis `( ... )` are used instead of curly parenthesis `{ ... }` to wrap the catch statement instructions (then the catch instructions are programmed with the usual syntax and separated by semicolons `;`).
+(The maximum number of catch statements that can be programmed for constructor-try blocks is specified by the [macroref CONTRACT_LIMIT_CONSTRUCTOR_TRY_BLOCK_CATCHES] macro.)
+
+In the following example the constructor uses a function-try block to throw only `out_of_memory` and `error` exceptions while the destructor uses exception specifications to throw no exception (see also [file example/contracts exception_array.cpp]):
+
+[import ../example/contracts/exception_array.cpp]
+[exception_array]
+
+(The `BOOST_IDENTITY_TYPE` macro can be used to wrap the catch statement exception declaration types if they contain unwrapped commas.)
+
+Exception specifications and function-try blocks apply only to exceptions thrown by the function body and not to exceptions thrown by the contracts themselves (if any) and by the contract checking code generated by this library macros.
+[footnote
+*Rationale.*
+__N1962__ specifies that function-try blocks should only apply to the body code and not to the contract code.
+No explicit requirement is stated in __N1962__ for exception specifications but the authors have decided to adopt the same requirement that applies to function-try blocks (because it seemed of little use for the contract to throw an exception just so it is handled by the exception specification).
+]
+
+[endsect]
+
+[section Specifying Types (no Boost.Typeof)]
+
+This library uses __Boost_Typeof__ to automatically deduces postcondition old value types and constant assertion variable types.
+If programmers do not want the library to use __Boost_Typeof__ they can explicitly specify these types.
+
+The types of postcondition old values are specified instead of using `auto` and they must be wrapped within round parenthesis unless they are fundamental types containing no symbol (these must match the type of the specified old-of expressions):
+
+    (``/type/``) ``/variable/`` = CONTRACT_OLDOF ``/oldof-expression/``
+
+The types of constant assertion variables are specified just before each variable name and they also must be wrapped within round parenthesis unless they are fundamental types containing no symbol:
+
+    const( (``/type1/``) ``/variable1/``, (``/type2/``) ``/variable2/``, ... ) ``/boolean-expression/``
+
+For example (see also [file example/contracts typed_counter.cpp]):
+
+[import ../example/contracts/typed_counter.cpp]
+[typed_counter]
+
+Note that postcondition result values are always specified using `auto`:
+
+    auto ``/result-variable/`` = return
+    
+This is because the function return type is know by the library as specified in the function declaration within the [macroref CONTRACT_FUNCTION] macro.
+Therefore, the postcondition result value type is never explicitly specified by programmers (but __Boost_Typeof__ is never used to deduce it).
+
+[note
+It is recommended to not specify these types explicitly and let the library internally use __Boost_Typeof__ to deduce them because the library syntax is more readable without the explicit types.
+However, all types must be properly registered with __Boost_Typeof__ as usual in order to use type-of emulation mode on __CXX03__ compilers that do not support native type-of (see __Boost_Typeof__ for more information).
+]
+
+[endsect]
+
+[section Block Invariants and Loop Variants]
+
+/Block invariants/ can be used anywhere within the function body and they are used to assert correctness conditions of the implementation (very much like `assert`).
+They are programmed specifying a list of assertions to the [macroref CONTRACT_BLOCK_INVARIANT] macro (including static, constant, and select assertions):
+
+    CONTRACT_BLOCK_INVARIANT( ``/assertion1/``, ``/assertion2/``, ... )
+
+When block invariants are used within a loop, they are also called /loop invariants/ (e.g., __Eiffel__ uses this terminology).
+
+Furthermore, this library allows to specify [@http://en.wikipedia.org/wiki/Loop_variant ['loop variants]].
+A loop variant is a non-negative monotonically decreasing number that is updated at each iteration of the loop.
+The specified loop variant expression is calculated by this library at each iteration of the loop and it is automatically asserted to be non-negative (`>= 0`) and to decrease monotonically from the previous loop iteration.
+Because the loop variant monotonically decreases and it cannot be smaller than zero, either the loop terminates or one of the two library assertions will eventually fail in which case the library will call the [funcref contract::loop_variant_broken] handler therefore detecting and stopping infinite loops.
+Each given loop can only have one variant which is specified using the [macroref CONTRACT_LOOP_VARIANT] macro.
+The enclosing loop (`while`, `for`, `do`, etc) must be declared using the [macroref CONTRACT_LOOP] macro:
+
+    CONTRACT_LOOP( ``/loop-declaration/`` ) {
+        CONTRACT_LOOP_VARIANT( ``/non-negative-monotonically-decreasing-expression/`` )
+        ...
+    }
+
+Note that the library cannot automatically make constant any of the variables within the function body therefore constant block invariant assertions and constant loop variant expressions should be used by programmers if they want to enforce constant-correctness for block invariants and loop variants.
+
+The following example uses a loop to calculate the [@http://en.wikipedia.org/wiki/Greatest_common_divisor Greatest Common Divisor (GCD)] of two integral numbers (see also [file example/contracts blockinv_loopvar_gcd.cpp]):
+
+[import ../example/contracts/blockinv_loopvar_gcd.cpp]
+[blockinv_loopvar_gcd]
+
+__Eiffel__ supports loop variants but __N1962__ does not.
+Loop variants might not be very useful especially if __Boost_Foreach__ or similar constructs are used to ensure loop termination.

+When a contract assertion fails, this library prints a message on the standard error `std::cerr` and it terminates the program calling `std::terminate`.
+Programmers can change this behavior customizing the actions that the library takes on contract assertion failure by setting the contract broken handler functions.
+By default the library terminates the program because a contract failure indicates that the program is in an invalid state that programmers specified it should never happen (so the only sensible assumption is that the program execution should not continue).
+However, in some cases programmers might need to handle even such catastrophic failures by executing some fail-safe code instead of terminating the program and that can be done customizing the contract broken handlers.
+
+The library functions [funcref contract::set_precondition_broken], [funcref contract::set_postcondition_broken], [funcref contract::set_class_invariant_broken], [funcref contract::set_block_invariant_broken], and [funcref contract::set_loop_variant_broken] can be used to customize the action to taken in case of precondition, postcondition, class invariant, block invariant, and loop variant failure respectively.
+Furthermore, class invariants are checked at entry, at normal exit, and at exit but when exceptions are thrown so more granular handlers can be set for each of these cases using [funcref contract::set_class_invariant_broken_on_entry], [funcref contract::set_class_invariant_broken_on_exit], and [funcref contract::set_class_invariant_broken_on_throw] (using [funcref contract::set_class_invariant_broken] is equivalent to setting all these class invariant broken handles to the same handler).
+[footnote
+__N1962__ does not allow to configure class invariant broken handlers differently for entry, exit, and throw.
+]
+
+This library passes a parameter of type [enumref contract::from] to the contract broken handler functions indicating the context that failed the contract assertion (e.g., this parameter will be set to `contract::FROM_DESTRUCTOR` if the contract assertion failed from a destructor):
+[footnote
+The `contract::from` parameter was not part of __N1962__ contract broken handlers but the proposal hinted that it might be needed (need that was confirmed by the implementation of this library).
+]
+
+    void ``/contract-broken-handler/`` ( contract::from const& context )
+
+[important
+In order to comply with the STL exception safety requirements, destructors should never throw.
+Therefore, even if programmers customize the contract broken handlers to throw exceptions instead of terminating, the handlers should never throw when contract assertions fail from a destructor (and the [enumref contract::from] parameter can be used to discriminate this case).
+]
+
+The contract broken handlers are always invoked with an active exception that refers to the exception that failed the contract:
+[footnote
+*Rationale.*
+Exceptions are used to signal a contract assertion failure because it is not possible to directly call the contract broken handler ([funcref contract::precondition_broken], etc) instead of throwing the exception in oder to properly implement subcontracting.
+For example, if an overriding precondition fails but the overridden precondition is true then the library will not call the broken handler even if the overriding precondition threw an exception (as required by subcontracting).
+Contract assertion failures are critical error conditions so it is actually natural that the library uses exceptions to signal them (note that the library will always handle the exceptions by calling the contract broken handlers which terminate the program by default so the fact that the library signals contract assertion failures using exceptions does not imply that an exception will be thrown if a contract assertion fails, that is entirely decided by the implementation of the broken handlers).
+]
+
+# Either an exception that was explicitly thrown by the user from the contract (e.g. `not_a_number` in the example blow).
+# Or, an exception that was thrown ["behind the scene] while evaluating a contract assertion (e.g., the assertion calls an STL algorithm and that throws `std::bad_alloc`).
+# Or, an exception automatically thrown by this library in case a contract assertion is evaluated to be false (these exceptions are always [classref contract::broken] objects and they contained detailed information about the contract assertion that was evaluated to be false: file name, line number, assertion number, and assertion code).
+[footnote
+The assertion number is meaningful only within a specific handler.
+For example, if assertion number `2` failed within the class invariant broken handler that mean that the class invariant number `2` failed.
+Therefore, the assertion number is not useful if a single handler is programmed for all types of contracts because such an handler can no longer distinguish between class invariants, preconditions, postconditions, etc.
+]
+
+In all these cases the contract assertion is considered failed because it was not evaluated to be true (and that is the case not only for assertions that are evaluated to be false but also for assertions that throw exceptions while being evaluated).
+[footnote
+*Rationale.*
+Threating an exception thrown while evaluating an assertion as a failure of the contract assertion is a clear policy established by this library under the principle that a contract assertion fails unless it is evaluated to be true.
+__N1962__ does not completely clarify this point.
+]
+The customized contract broken handlers can re-throw the active exception and catch it so to inspect it for logging or for any other customized behaviour that might need to be implemented by the programmers.
+
+The following example customizes the contract broken handlers to throw exceptions (both user-defined exceptions like `not_a_number` and the [classref contract::broken] exception that the library automatically throws in case of a contract assertion failure).
+However, the customized handlers never throw from within a destructor to comply with STL exception safety requirements (see also [file example/contracts broken_handler_sqrt.cpp]):
+[footnote
+In this example, contract failures from destructors are logged and then simply ignored.
+That might be acceptable in this simple example but it is probably a very bad idea in general.
+]
+
+[import ../example/contracts/broken_handler_sqrt.cpp]
+[broken_handler_sqrt]
+
+Note how the ternary operator `:?` can be used to program assertions that throw exceptions on failure:
+
+    x >= 0.0 ? true : throw not_a_number
+
+Then the contract broken handlers are customized to propagate the exceptions instead of handling them by calling `std::terminate` (default behaviour).
+
+See also [file example/contracts contract_failure.cpp] for a more complex example that redefines the contract broken handlers to throw exceptions in order to automatically check that the correct contract broken handlers are called when assertions fail in accordance with the call semantics explained in the __Contract_Programming_Overview__ section.

+[section Concepts]
+
+This section explains how to use this library to check concepts.
+Concepts are part of the program specifications because they enforce requirements on generic types at compile-time and therefore they are within the scope of this library.
+
+Concepts were proposed for addition to __CXX11__ but they were unfortunately never adopted (see __N2081__).
+The concepts that are checked using this library need to be defined using the __Boost_ConceptCheck__ library.
+This library does not add any extra functionality with respect to the concept checking features already provided by __Boost_ConceptCheck__ but it allows to specify both concepts and contracts together within a unified syntax.
+
+[section Class Templates]
+
+It is possible to list the concepts to check for class templates using `requires` within the [macroref CONTRACT_CLASS] macro, after the template parameter declarations (see also the __Grammar__ section):
+
+    template( ``/template-parameter1/``, ``/template-parameter2/``, ... ) requires( ``/concept1/``, ``/concept2/``, ... )
+
+The following example requires that the generic type `T` specified for the class template `vector` is always __CopyConstructible__ and it uses the `boost::CopyConstructible` concept defined by __Boost_ConceptCheck__ (see also [file example/concepts class_member_concept_vector.hpp], [file example/concepts class_member_concept_vector_error.cpp], and [file example/concepts class_member_concept_vector.cpp]):
+
+[import ../example/concepts/class_member_concept_vector.hpp]
+[class_member_concept_vector_class]
+
+If the class template `vector` is instantiated on a type `T` that is not __CopyConstructible__, the compiler will generate an error (with the usual format of __Boost_ConceptCheck__ errors).
+
+[endsect]
+
+[section Function Templates]
+
+It is possible to list concepts to check for function templates using `requires` within the [macroref CONTRACT_FUNCTION] macro, after the template parameter declarations (see also the __Grammar__ section).
+
+For example, for a constructor function template (see also [file example/concepts class_member_concept_vector.hpp], [file example/concepts class_member_concept_vector_constructor_error.cpp], and [file example/concepts class_member_concept_vector.cpp]):
+
+[class_member_concept_vector_constructor]
+
+And, for a member function template (see also [file example/concepts class_member_concept_vector.hpp], [file example/concepts class_member_concept_vector_member_error.cpp], and [file example/concepts class_member_concept_vector.cpp]):
+
+[class_member_concept_vector_member]
+
+If the `vector` constructor template or the `vector::insert` member function template are instantiated on a type `Iterator` that is not an __InputIterator__, the compiler will generate an error (with the usual format of __Boost_ConceptCheck__ errors).
+
+So far we have used concepts that are predefined by __Boost_ConceptCheck__ but it is also possible to check user-defined concepts as long as they are defined using __Boost_ConceptCheck__.
+For example, consider the following user-defined `Addable` concept (see also [file example/concepts free_concept_operator_preinc.hpp], [file example/concepts free_concept_operator_preinc_error.cpp], and [file example/concepts free_concept_operator_preinc.cpp]):
+
+[import ../example/concepts/free_concept_operator_preinc.hpp]
+[free_concept_operator_preinc]
+
+If this templated operator `++` is instantiated on a type `T` that is not __Assignable__ or not `Addable`, the compiler will generate an error (with the usual format of __Boost_ConceptCheck__ error).
+
+Note that concepts can also be specified for free function templates, for free operator templates, and for member operator templates (as illustrated in some of the above examples).
+
+[endsect]
+
+[section Concept Definitions (Not Implemented)]
+
+Using the preprocessor parsing techniques introduced by the library, it should be possible to implement the following syntax to define [@http://en.wikipedia.org/wiki/Concepts_(C%2B%2B) concepts].
+Note how this syntax resembles the syntax proposed by __N2081__ for adding concepts to __CXX11__ (__N2081__ and concepts were unfortunately not adopted by the standard committee).

+                op(x, op(y, z)) == op(op(x, y), z);
+            )
+        )
+    )
+
+Note that:
+
+# Parenthesis around function parameter types can be always allowed but they should be required only when the parameter name is also specified.
+# The function bodies need to be specified within the macros and that will make compiler errors very hard to use (because the errors will all refer to the same line number, the line number on which the `CONTRACT_CONCEPT` macro expanded).
+However, concept definitions, including possible function bodies, might be simple enough for this not to be a major issue at least in the most common cases (the authors do not have enough experience with programming concept definitions to truly assess this).
+
+The authors /think/ this syntax can be implemented and parsed using the preprocessor however the authors have not tried to implement this yet.
+If this syntax can indeed be implemented, it should then be investigated if the actual concept definitions can be programmed from the parsed concept traits using C++ (this seems possible at least for __CXX11__ based on some work done for the [@http://zao.se/~zao/boostcon/11/slides/Boost.Generic.pdf Generic] library).
+
+The authors recognize that implementing concept definitions would be a nice addition to this library (again, concepts are parts of the program specifications, they are contracts on the type system that are checked at compile-time, so both concept checking and concept definition are within the scope of this library).
+However, at the moment there are no concrete plans for extending this library with the concept definitions (see also [@https://sourceforge.net/apps/trac/contractpp/ticket/49 Ticket 49]).
+
+The following is a side-by-side comparison of this possible concept definition syntax with the syntax proposed by __N2081__:
+
+[import ../example/concepts/concept_def.cpp]
+[import ../example/concepts/concept_def_npaper.cpp]
+[table
+[ [Possible Extension of This Library (not implemented)] [\[N2081\] Proposal (not part of C++)] ]
+[ [[concept_def]] [[concept_def_npaper]] ]
+]
+
+Note that:
+
+# Extra wrapping parenthesis are used when expressions contain unwrapped commas `,` or leading symbols.
+# The specifiers `constructor`, `destructor`, and `member` follow the same syntax as the [macroref CONTRACT_CONSTRUCTOR_BODY] and [macroref CONTRACT_DESTRUCTOR_BODY], and they serve a purpose similar to these macros in naming the constructors, destructors, and member functions outside class declarations.
+
+If concept definitions were added to this library, concepts would still be checked using the `requires` specifier in class and function declarations as we have seen so far (it might even be possible for concepts defines using __Boost_ConceptCheck__ to be still specified using some type tagging of this library concept types to internally distinguish between __Boost_ConceptCheck__ concepts and concepts define using this library).
+Furthermore, this library could provide all the standard concepts defined in __N2914__ in an header file =contract/std/concept.hpp=.

+[:['--Hoare (see __Hoare73__)]]
+
+This section gives an overview of Contract Programming (see __Meyer97__, __Mitchell02__, and __N1613__ for a detailed introduction to Contract Programming).
+
+[note
+The objective of this library is /not/ to convince programmers to use Contract Programming.
+It is assumed that programmes understand the benefits and trade-offs associated with Contract Programming and they have already decided to use this methodology to formally program specifications.
+Then, this library aims to be the best Contract Programming library for C++.
+]
+
+[section Assertions]
+
+Contract Programming is characterized by the following type of assertion mechanisms.
+
+[table
+[ [Assertion] [Purpose] ]
+[ [Preconditions] [
+These are logical conditions that programmers expect to be true when the function is called (e.g., to check constraints on the function arguments).
+] ]
+[ [Postconditions] [
+These are logical conditions that programmers expect to be true when the  function has ended normally (e.g., to check the result and any side effect that a function might have).
+Postconditions can usually access the function result value (for non-void functions) and /old values/ that expressions had before the body execution.
+] ]
+[ [Class Invariants] [
+These are logical conditions that programmers expect to be true after the constructor has been executed successfully, before and after the execution of every non-static public member function, and before the destructor is executed (e.g, class invariants can define valid states of all objects of a class).
+It is possible to describe a different set of class invariants for volatile member functions but /volatile class invariants/ are assumed to be same as class invariants unless differently specified.
+It is also possible to describe /static class invariants/ which are excepted to be true before and after the execution of any public member function (even if static), including constructor entry and destructor exit.
+[footnote
+*Rationale.*
+Static and volatile class invariants were first introduced by this library to reflect the fact that C++ support both static and volatile member functions.
+Static and volatile class invariants are not part of __N1962__.
+]
+] ]
+[ [Subcontracting] [
+Subcontracting is defined using the __substitution_principle__ and it predicates that: Preconditions cannot be strengthen, postconditions and class invariants cannot be weaken.
+] ]
+[ [Block Invariants] [
+These are logical conditions that programmers except to be true every time the execution reaches the point where the condition is asserted.
+When used within a loop (i.e., a block of code that can be executed in iteration), block invariants are also called /loop invariants/ and they assert conditions that are expected to be true for every loop iteration.
+] ]
+[ [Loop Variants] [
+For a given loop, a [@http://en.wikipedia.org/wiki/Loop_variant loop variant] is a non-negative integer expression (`>= 0`) with a value that is expected to decrease at every subsequent loop iteration.
+Loop variants are used to ensure that loops terminate avoiding infinite iterations.
+] ]
+]
+
+It is a common Contract Programming requirement to disable other contracts while a contract assertions is being evaluated (in order to avoid infinite recursive calls).
+This library implement this feature however it should be noted that in order to globally disable assertions while checking another assertion, some type of global variable needs to be used.
+In multi-threaded environments, programmers can define the [macroref CONTRACT_CONFIG_THREAD_SAFE] configuration macro to protect such a global variable from racing conditions (but that will effectively introduce a global lock in the program).
+
+A limited form of Contract Programming is the use of the C++ `assert` macro.
+Using `assert` is common practice for many programmers but unfortunately it suffers from the following problems (that are instead resolved by using Contract Programming):
+
+# `assert` is used within the implementation therefore the asserted conditions are not easily visible to the caller which is only familiar with the class and function declarations.
+# `assert` does not distinguish between preconditions and postconditions.
+In well-tested production code, postconditions can be disabled trusting the correctness of the implementation while preconditions might still need to remain enabled because of the evolution of the calling code.
+Using `assert` it is not possible to selectively disable only postconditions and all assertions must be disabled at once.
+# `assert` requires to manually program extra code to check class invariants (e.g., extra member functions and try blocks).
+# `assert` does not support subcontracting.
+
+[endsect]
+
+[section Benefits]
+
+The main use of Contract Programming is to improve software quality.
+__Meyer97__ discusses how Contract Programming can be used as the basic tool to write ["correct] software.
+Furhtermore, __Stroustrup97__ discusses the key importance of class invariants plus advantages and disadvantages of preconditions and postconditions.
+The following is a short summary of the benefits associated with Contract Programming mainly taken from __N1613__.
+
+[table
+[ [#] [Topic] [Benefit] ]
+[ [1.] [Preconditions and Postconditions] [
+Using function preconditions and postconditions, programmers can give a precise semantic description of what a function requires at its entry and what it ensures under its (normal) exit.
+In particular, using postcondition old values, Contract Programming provides a mechanism that allows programmers to compare values of an expression before and after the function body execution.
+This mechanism is powerful enough to enable programmers to express many constraints within the code, constraints that would otherwise have to be captured at best only informally by the code documentation.
+] ]
+[ [2.] [Class Invariants] [
+Using class invariants, programmers can describe what to expect from a class and the logic dependencies between the class members.
+It is the job of the constructor to ensure that the class invariants are satisfied when the object is first created.
+Then the implementation of the member functions can be largely simplified as they can be written knowing that the class invariants are satisfied because Contract Programing checks them before and after the execution of every member function. 
+Finally, the destructor makes sure that the class invariants hold for the entire life of the object, checking the class invariants one last time before the object is destructed.
+] ]
+[ [3.] [Self-Documenting Code] [
+Contracts are part of the source code, they are executed and verified at run-time so they are always up to date with the code itself.
+Therefore the specifications, as documented by the contracts, can be trusted to always be up to date with the implementation code.
+] ]
+[ [4.] [Easier Debugging] [
+Contract Programming can provide a powerful debugging facility because, if contracts are well written, bugs will cause contract assertions to fail exactly where the problem first occurs instead than at some later stage of the program execution in an apparently unrelated manner.
+Note that a precondition failure points to a bug in the function caller, a postcondition failure points instead to a bug in the function implementation. 
+Furthermore, in case of contract failure, this library provides detailed error messages that greatly helps debugging.
+[footnote Of course, if the contract is ill written then Contract Programming is of little use.
+However, it is less likely to have a bug in both the function body and the contract than in the function body only.
+For example, consider the validation of a result in postconditions.
+Validating the return value might seem redundant, but in this case we actually want that redundancy.
+When programmers write a function, there is a certain probability that they make a mistake in implementing the function body.
+When programmers specify the result of the function in the postconditions, there is also a certain probability that they make a mistake in writing the contract. 
+However, the probability that programmers make a mistake twice (in both the body /and/ the contract) is lower than the probability that the mistake is made just once (in either the body or the contract).]
+] ]
+[ [5.] [Easier Testing] [
+Contract Programming facilitates testing because a contract naturally specifies what a test should check.
+For example, preconditions of a function state which inputs cause the function to fail and postconditions state which outputs are produced by the function on normal exit.
+] ]
+[ [6.] [Formal Design] [
+Contract Programming can serve to reduce the gap between designers and programmers by providing a precise and unambiguous specification language.
+Moreover, contracts can make code reviews easier.
+] ]
+[ [7.] [Formal Inheritance] [
+Contract Programming formalizes the virtual function overriding mechanism using subcontracting as justified by the __substitution_principle__.
+This keeps the base class programmers in control as overriding functions still have to fully satisfy the base class contracts.
+] ]
+[ [8.] [Replace Defensive Programming] [
+Contract Programming assertions can replace [@http://en.wikipedia.org/wiki/Defensive_programming Defensive Programming] checks localizing these checks within the contract and making the code more readable.
+] ]
+]
+
+[endsect]
+
+[section Costs]
+
+Contract Programming benefits come to the cost of performance as discussed in detail by both __Stroustrup97__ and __Meyer97__.
+However, while performance trade-offs should be carefully considered depending on the specific application domain, software quality cannot be sacrificed (it is difficult to see the value of software that quickly and efficiently provides an incorrect result).
+
+The run-time performances are negatively impacted by Contract Programming mainly because of the following:
+
+# The extra processing required to check the assertions.
+# The extra processing required by the additional function calls (additional functions are invoked to check preconditions, postconditions, class invariants, etc).
+# The extra processing required to copy expression results when old values that are used in postconditions.
+
+To mitigate the run-time performance impact, programmers can selectively turn off some of the contract compilation and the related run-time checking.
+Programmers will have to decide based on the performance trade-offs required by their applications but a reasonable approach usually is to:
+
+* Always write contracts to clarify the semantics of the design embedding the specifications directly into the code and making the code self-documenting.
+* Enable preconditions, postconditions, and class invariants compilation and checking during initial testing.
+* Enable only preconditions (and possibly class invariants) during release testing and for the final release (see also [macroref CONTRACT_CONFIG_NO_PRECONDITIONS], [macroref CONTRACT_CONFIG_NO_POSTCONDITIONS], and [macroref CONTRACT_CONFIG_NO_CLASS_INVARIANTS]).
+
+This approach is usually reasonable because in well-tested production code, validating the function body implementation using postconditions and class invariants is rarely needed since the function has shown itself to be ["correct] during testing.
+On the other hand, checking function arguments using postconditions is always needed because of the evolution of the calling code.
+Furthermore, postconditions are usually computationally more expensive to check (see the __Assertion_Requirements__ section for a mechanism to selectively enable assertions also based on their computational complexity).
+
+Compile-time performances are also impacted by this library mainly because:
+
+# The contracts appear in class and function declarations (usually header files) so they have to be re-compiled for each translation unit.
+# The library implementation extensively uses preprocessor and template meta-programming which significantly stress compiler performances.
+
+[#compilation_time_warning_anchor]
+[warning
+Unfortunately, the current implementation of this library significantly slows down compilation.
+For example, for a project with 122 files and 15,471 lines of code, adding contracts to a total of 50 classes and 302 functions increased compilation time from 1 minute to 26 minutes when compilation was enabled for all contracts, and from 1 minute to 2 minutes when contracts were left in the code but contract compilation was disabled using this library configuration macros `CONTRACT_CONFIG_NO_...`.
+[footnote
+This library macros always need to expand to generate the class and function declarations even when contract compilation is disabled.
+That is why there is a compile-time overhead, even if significantly smaller, also when contracts are all disabled (in this case however there is zero run-time overhead).
+The compilation time overhead when all contracts are turned off could be further reduced by optimizing the library implementation to not include internal headers that are not required when contracts are off (this type of optimizations will be a major focus on future releases).
+]
+
+On compilers that support [@http://en.wikipedia.org/wiki/Precompiled_header pre-compiled headers] (GCC, MSVC, etc), these can be used to reduce re-compilation time.
+For example, re-compilation time of [link contract__.examples.__n1962___vector__comparison_with_c___proposed_syntax =vector.cpp=] from the __Examples__ section is reduced from 44 seconds to 24 seconds (55% faster) when its header [link contract__.examples.__n1962___vector__comparison_with_c___proposed_syntax =vector.hpp=] is pre-compiled (with all contracts enabled).
+[footnote
+There is essentially no gain in pre-compiling this library headers because most of the compilation time is taken by expanding and compiling this library macros as they appear in the user code (and not by the library implementation code itself).
+Furthermore, pre-compiled headers should be used with the usual care because they can complicate the build system and they introduce extra dependencies that might limit the amount of targets that can be built simultaneously in a parallel build.
+However, if properly used, pre-compiled headers can significantly reduce re-compilation time when using this library.
+]
+
+The authors have not done a detailed preprocessing-time and compile-time analysis of the performances of this library.
+Therefore, the authors have not yet tried to optimize this library compilation-time.
+Reducing compilation-time will be a major focus of future releases (see also [@https://sourceforge.net/apps/trac/contractpp/ticket/48 Ticket 48]).
+]
+
+Finally, Contract Programming should be seen as a tool to complement (and not to substitute) testing.

+
+[section Free Function Calls]
+
+A /free function/
+[footnote
+In C++, a free function is any function that is not a member function.
+]
+call executes the following steps:
+
+# Check the function preconditions.
+# Execute the function body.
+# Check the function postconditions.
+
+[endsect]
+
+[section Member Function Calls]
+
+A member function call executes the following steps:
+
+# Check the static class invariants.
+# Check the non-static class invariants (in __logic_and__ with the base class invariants when subcontracting).
+These are checked only for non-static member functions.
+[footnote
+Static member functions cannot be virtual so they cannot be overridden and they do not subcontract.
+]
+Volatile member functions check volatile class invariants instead.
+# Check the function preconditions (in __logic_or__ with the overridden function preconditions when subcontracting).
+# Execute the function body.
+# Check the static class invariants (even if the body throws an exception).
+# Check the non-static class invariants (in __logic_and__ with the base class invariants when subcontracting).
+These are checked only for non-static member functions and even if the body throws an exception.
+Volatile member functions check volatile class invariants instead.
+# Check the function postconditions (in __logic_and__ with the overridden function postconditions when subcontracting).
+These are checked only if the body does not throw an exception.
+
+[#logic_and_anchor] [#logic_or_anchor]
+In this documentation __logic_and__ and __logic_or__ are the logic /and/ and /or/ operations evaluated in short-circuit:
+
+* `p` __logic_and__ `q` is true if and only if both `p` and `q` are true but `q` is evaluated only when `p` is true.
+* `p` __logic_or__ `q` is true if and only if either `p` or `q` is true but `q` is evaluated only when `p` is false.
+
+Class invariants are checked before preconditions and postconditions so that preconditions and postconditions assertions can be simplified by being programmed under the assumption that class invariants are satisfied (e.g., if class invariants assert that a pointer cannot be null then preconditions and postconditions can safety dereference the pointer without additional checking).
+Similarly, subcontracting checks contracts of base classes before checking the derived class contracts so that the base class contract can be programmed under the assumption that the base class contracts are satisfied.
+When a member function overrides more than one virtual base function because of multiple inheritance:
+
+* Class invariants are checked in __logic_and__ with the class invariants of all base classes following the inheritance order.
+* Preconditions are checked in __logic_or__ with the preconditions of all overridden functions following the inheritance order.
+* Postconditions are checked in __logic_and__ with the postconditions of all overridden functions following the inheritance order.
+
+Note that:
+
+* Preconditions and postconditions of static member functions cannot access the object.
+* Preconditions, postconditions, and volatile class invariants of volatile member functions access the object as (constant) volatile.
+
+[endsect]
+
+[section Constructor Calls]
+
+A constructor call executes the following steps:
+
+# Check the constructor preconditions.
+# Initialize base classes and members executing the constructor member initialization list if present.
+# Check the static class invariants (but not the non-static class invariants).
+# Execute the constructor body.
+# Check the static class invariants (even if the body throws an exception).
+# Check the non-static class invariants, but only if the body did not throw an exception.
+# Check the constructor postconditions, but only if the body did not throw an exception.
+
+Preconditions are checked before initializing base classes and members so that these initializations can relay on preconditions to be true (for example to validate constructor arguments before they are used to initialize member variables).
+C++ object construction mechanism will automatically check base class contracts when subcontracting.
+
+Note that:
+
+* Non-static class invariants are not checked at constructor entry (because there is no object before the constructor body is executed).
+* Preconditions cannot access the object (because there is no object before the constructor body is executed).
+* Postconditions cannot access the object old value (because there was no object before the constructor body was executed).
+* The object is never volatile within constructors so constructors do not check volatile class invariants.
+
+[endsect]
+
+[section Destructor Calls]
+
+A destructor call executes the following steps:
+
+# Check the static class invariants.
+# Check the non-static class invariants.
+# Execute the destructor body.
+# Check the static class invariants (even if the body throws an exception).
+[footnote
+For generality, this library does not require the destructor body to not throw exceptions.
+However, in order to comply with the STL exception safety requirements, destructors should never throw.
+]
+# Check the non-static class invariants, but only if the body threw an exception.
+
+C++ object destruction mechanism will automatically check base class contracts when subcontracting.
+
+Note that:
+
+* Destructors have no parameter and they can be called at any time after object construction so they have no preconditions.
+* After the destructor body is executed, the object no longer exists so non-static class invariants do not have to be true and they are not checked at destructor exit.
+* Destructors have no postconditions because they have no parameter and after the body execution there is no object.
+[footnote
+In theory, destructors could have static postconditions (i.e., postconditions that are not allowed to access the object which no longer exists after destruction).
+Still destructors shall never have preconditions because a destructor can be called at any point after the object is constructed as long the class invariants hold.
+None of the Contract Programming references that the authors have studied propose static postconditions for destructor (neither __N1962__ nor __Meyer97__, but __Eiffel__ has no static data member).
+Future revisions of this library might implement destructor static postconditions (e.g., a destructor postconditions of a class that counts object instances could assert that the instance counter stored in a static data member should be decreased of one because the object has been destructed, see also [@https://sourceforge.net/apps/trac/contractpp/ticket/41 Ticket 41]).
+]
+* The object is never volatile within destructors so destructors do not check volatile class invariants.
+
+[endsect]
+
+[section Constant-Correctness]
+
+Contracts are only responsible to check the program state in oder to ensure its compliance with the specifications.
+Therefore, contracts should not be able to modify the program state and exclusively "read-only" operations (or /queries/) should be used to program contracts.
+
+This library enforces this constraint at compile-time using C++ `const` qualifier.
+[footnote
+As usual in C++, constant-correctness can be enforced at compile-time only as long as programmers do not use `const_cast` and `mutable`.
+]
+Contracts only have access to the object, function arguments, and function return value via constant references `const&` or pointers `const*`.
+Other variables (static data members, global variables, etc) can be explicitly made constant using /constant assertions/ (see the __Advanced_Topics__ section).
+
+[endsect]
+
+[section Specification vs. Implementation]
+
+Contracts are part of the program specification and not of its implementation.
+Therefore, contracts should appear within C++ declarations and not within definitions.
+[footnote
+This is a major conceptual difference with respect to [@http://en.wikipedia.org/wiki/Defensive_programming Defensive Programming] and using `assert` because they program assertions within the function body instead that with the function declaration.
+]
+
+Contracts are most useful when they assert conditions only using public members.
+For example, the caller of a member function cannot in general make sure that the member function preconditions are satisfied if these preconditions use private members that are not accessible by the caller.
+Therefore, a failure in the preconditions will not necessarily indicate a bug in the caller given that the caller was not able to fully check the preconditions before calling the member function.
+In most cases, the need of using non-public members to check contracts indicates an error in the design of the class.
+However, given that C++ provides programmers ways around access level restrictions (e.g., `friend` and function pointers), this library leaves it up to the programmers to make sure that only public members are used in contract assertions (__N1962__ follows the same approach not forcing contracts to only use public members, __Eiffel__ instead generates a compiler error if preconditions use non-public members).
+[footnote
+*Rationale.*
+In theory, if C++ [@http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#45 defect 45] were not fixed, this library could have generated a compile-time error for preconditions that use non-public members.
+]
+
+Finally, only public member functions shall check class invariants.
+Private and protected member functions are allowed to brake class invariants because private and protected member are part of the class implementation and not of its specification.
+
+[endsect]
+
+[section Broken Contracts]
+
+After programmers specify contracts, this library automatically checks preconditions, postconditions, class invariants, block invariants, and loop variants at run-time.
+If a precondition, postcondition, class invariant, block invariants, or loop variant is checked to be false or throws an exception then the library invokes the [funcref contract::precondition_broken], [funcref contract::postcondition_broken], [funcref contract::class_invariant_broken_on_entry] or [funcref contract::class_invariant_broken_on_exit] or [funcref contract::class_invariant_broken_on_throw], [funcref contract::block_invariant_broken], and [funcref contract::loop_variant_broken] function respectively.
+
+These function invoke `std::terminate()` by default but programmers can redefine them to take a different action (throw an exception, exit the program, etc) using [funcref contract::set_precondition_broken], [funcref contract::set_postcondition_broken], [funcref contract::set_class_invariant_broken], [funcref contract::set_block_invariant_broken], and [funcref contract::set_loop_variant_broken] (this mechanism is similar to the one of C++'s `std::terminate()`).
+See the __Contract_Broken_Handlers__ section for an example.
+
+[endsect]
+
+[section Features]

+The Digital Mars C++ compiler extends C++ adding Contract Programming language support (among many other features).
+] ]
+[ [__Lindrud04__] [C++] [

+Interestingly, these contract macros automatically generate __Doxygen__ documentation
+[footnote
+*Rationale.*
+Older versions of this library used to automatically generate __Doxygen__ documentation from the contract macros.
+This functionality was abandoned for a number of reasons: this library macros became too complex and the __Doxygen__ preprocessor is no longer able to expand them; the __Doxygen__ documentation was just a repeat of the contract code (so programmers can directly look at contracts in the header files), __Doxygen__ might not necessarily be the documentation tool chosen by all programmers.
+]
+but old values, class invariants, and subcontracting are not supported plus contracts are specified within definitions instead of declarations (unfortunately, these missing features are all essential to Contract Programming).
+] ]
+[ [__Maley99__] [C++] [
+This supports Contract Programming including subcontracting but with some limitations (e.g., programmers need to manually build an inheritance tree using artificial template parameters), it does not use macros so programmers are required to write by hand a significant amount of boiler-plate code.
+(The authors have found this work very inspiring when they started to develop this library.)
+] ]
+[ [__C2__] [C++] [

+]
+
+Typically, preprocessing tools external to the language work by transforming specially formatted code comments into contract code that is then checked at run-time.
+One of this library primary goals was to support Contract Programming entirely within C++ and without using any tool external to the standard language (C++ macros were used instead of external preprocessing tools).
+
+To the authors' knowledge, this the only library that fully support Contract Programming for C++ (see the __Bibliography__ section for the complete list of Contract Programming references studied by the authors).

+
+[section Getting Started]
+
+This section explains how to setup a system to use this library.
+
+[section This Documentation]
+
+Programmers should have enough knowledge to use this library after reading the __Introduction__, __Getting_Started__, and __Tutorial__ sections.
+The other sections can be consulted to gain a more in depth knowledge of the library.
+
+Some footnotes are marked by the word "*Rationale*". They explain reasons behind decisions made during the design and implementation of this library.
+
+In most of the examples presented in this documentation the Boost.Detail/LightweightTest macro `BOOST_TEST` is used to assert test conditions (see also =boost/detail/lightweight_test.hpp=).
+The `BOOST_TEST` macro is conceptually similar to C++ `assert` but a failure of the checked condition does not abort the program, instead it makes `boost::report_errors` return a non-zero program exit code.
+[footnote
+*Rationale.*
+Using Boost.Detail/LightweightTest allows to add the examples to the library regression tests so to make sure that they always compile and run correctly.
+]
+
+[endsect]
+
+[section Compilers and Platforms]
+
+The implementation of this library uses preprocessor and template meta-programming (as supported  by __Boost_Preprocessor__ and __Boost_MPL__ respectively), templates with partial specializations and function pointers (similarly to __Boost_Function__), and local functions (as supported by __Boost_LocalFunction__).
+The authors originally developed and tested the library on:
+
+# GCC 4.5.3 on Cygwin (with and without __CXX11__ features enabled =-std=c++0x=).
+[footnote
+When using GCC to compile large projects that use this library, it might be necessary to appropriately set the `--param gcc-min-expand` option to avoid internal compiler errors due to excessive virtual memory usage.
+]
+
+# Microsoft Visual C++ (MSVC) 8.0 on Windows XP and Windows 7.
+
+At present, the library has not been tested on other compilers or platforms.
+
+[endsect]
+
+[section Installation]
+
+This library is composed of header files only.
+Therefore there is no pre-compiled object file which needs to be installed or linked.
+Programmers can simply instruct the C++ compiler where to find the library header files and they can start compiling code using this library.
+
+[important
+This library extensively uses __Boost__ libraries.
+__Boost__ version 1.50 must be properly installed in order for this library to compile.
+]
+
+Let ['=ROOT=] be the root directory of this library installation then the directory structure is as follow:
+
+[pre
+['ROOT]/
+    doc/
+        html/   # This documentation.
+    example/    # Examples using this library.
+    include/    # This library source files (headers only).
+]
+
+For example, the following commands can be used to compile code using this library:
+[footnote
+For convenience, a =Jamfile.v2= file is provided in the example directory that can be used to compile and test all the examples using __Boost_Jam__.
+However, it is not necessary to use __Boost_Jam__ to compile code that uses this library.
+]
+
+[pre
+$ g++ -I ['ROOT]/include ...    # For GCC.
+> cl  /I ['ROOT]\include ...    # For MSVC.
+]
+
+All necessary library headers are included in the source code by the following instruction (it is not necessary to include single headers separately):
+
+    #include <contract.hpp> // Include this library headers.
+
+The following symbols are part of the library private interface, they are not documented, and they should not be directly used by programmers:
+[footnote
+*Rationale.*
+This library concatenates symbols specified by programmers (e.g., the function name) with other symbols (e.g., special prefixes and line numbers) to make internal symbols with unique names to avoid name clashes.
+These symbols are separated by the letter `X` when they are concatenated so they read more easily during debugging (unfortunately, the underscore character `_` could not be used instead of the letter `X` because if the original symbol already contained a leading or trailing underscore, the concatenation could result in a symbol with double underscores `__` which is reserved by the C++ standard).
+The ["aux] symbols are internal to the implementation of this library.
+The ["detail] symbols are not officially part of the library public interface and they are not documented however they constitute a separate set of standalone libraries that could be added to the library public interface in the future.
+]
+
+* Any symbol defined by files within the =contract/aux_/= or =contract/detail/= directories (these header files should not be directly included by programmers).
+* Any symbol within the `contract::aux` or `contract::detail` namespace.
+* Any symbol prefixed by `contract_aux_...` or `contract_detail_...` (regardless of its namespace).
+* Any symbol prefixed by `CONTRACT_AUX_...` or `CONTRACT_DETAIL_...` (regardless of its namespace).
+
+Symbols starting with `ERROR_...` are used to report compile-time errors via static assertions and programmers should not use these symbols to define macros or other constructs in the global namespace.
+
+[endsect]
+
+[section Disable Contract Compilation]
+
+Some of the library behaviour can be customized at compile-time by defining special /configuration macros/ (see [headerref contract/config.hpp]).
+In particular, the following configuration macros can be used to selectively turn on or off contract compilation and the related run-time checks:
+
+* Defining the [macroref CONTRACT_CONFIG_NO_PRECONDITIONS] macro turns off compilation and run-time checking of all preconditions.
+* Defining the [macroref CONTRACT_CONFIG_NO_POSTCONDITIONS] macro turns off compilation and run-time checking of all postconditions.
+* Defining the [macroref CONTRACT_CONFIG_NO_CLASS_INVARIANTS] macro turns off compilation and run-time checking of all class invariants.
+* Defining the [macroref CONTRACT_CONFIG_NO_BLOCK_INVARIANTS] macro turns off compilation and run-time checking of all block invariants.
+* Defining the [macroref CONTRACT_CONFIG_NO_LOOP_VARIANTS] macro turns off compilation and run-time checking of all loop variants.
+
+By default, all contracts are compiled and checked at run-time (i.e., all the macros above are not defined).
+
+[important
+In Contract Programming, it is usually important to selectively turn off contract compilation to reduce run-time, binary size, and compilation-time overhead associated with the contracts (see __Meyer97__).
+This library guarantees zero run-time and binary size overhead when all contracts are all turned off (however, even when contracts are all turned off there is a limited compile-time overhead associated with expanding the contract macros to generate the original class and function declarations).
+Note that when contracts are turned off their assertions are completely ignored by the compiler so the assertion code might not even be syntactically correct.
+]
+
+For example, the following commands compile and check preconditions and class invariants, but they do not compile and check postconditions, block invariants, and loop variants:
+
+[pre
+$ g++ -DCONTRACT_CONFIG_NO_POSTCONDITONS -DCONTRACT_CONFIG_NO_BLOCK_INVARIANTS -DCONTRACT_CONFIG_NO_LOOP_VARIANTS ...   # For GCC.
+> cl  /DCONTRACT_CONFIG_NO_POSTCONDITONS /DCONTRACT_CONFIG_NO_BLOCK_INVARIANTS /DCONTRACT_CONFIG_NO_LOOP_VARIANTS ...   # For MSVC.
+]
+
+Other configuration macros are provided to customize other aspects of the library.
+For example, the [macroref CONTRACT_CONFIG_FUNCTION_ARITY_MAX] macro is used to specify the maximum number of function parameters and the [macroref CONTRACT_CONFIG_INHERITANCE_MAX] macro is used to specify the maxim number of base classes.
+All configuration macros have appropriate default values when they are left undefined by programmers.

+[section Grammar]
+
+[:['["Almost every macro demonstrates a flaw in the programming language, in the program, or in the programmer.]]]
+[:['--Stroustrup (see __Stroustrup97__ page 160)]]
+
+This library uses macros to overcome a limitation of C++, namely the fact that the core language does not support preconditions, postconditions, class invariants, old values, and subcontracting.
+This section lists the complete grammar of the syntax used by this library macros.
+
+[#syntax_error_warning_anchor]
+[warning
+In general, an error in programming this library syntax will generate cryptic compiler errors (often exposing internal code from this library and from __Boost_Preprocessor__).
+[footnote
+Usually, the complexity of C++ definitions is greater than the complexity of C++ declaration and the fact that this library macros only affect declarations would help by preserving the usefulness of the compiler error messages for the definition code.
+However, this library aims to make declarations more complex by adding program specifications to them (preconditions, postconditions, etc).
+Therefore, it can no longer be argued that declarations are significantly simpler than definitions and it would be rather helpful to have sensible compiler error messages at least for the declarations with contracts.
+]
+
+There are intrinsic limitations on the amount of error checking that can be implemented by this library because it uses the preprocessor to parse its syntax (e.g., there is no way the preprocessor can gracefully detect and report unbalanced round parenthesis `( ... /* missing closing parenthesis here */` or an invalid concatenation symbol `BOOST_PP_CAT(xyz, ::std::vector)`).
+In addition, for a given macro all compiler error messages report the same line number (because macros always expand on a single line) so line numbers are not very useful in identifying syntactic errors.
+
+While the preprocessor imposes limits on the error checking that can be implemented, the current version of this library does not focus on providing the best possible syntax error messages (this will be the focus of future releases, see also [@https://sourceforge.net/apps/trac/contractpp/ticket/44 Ticket 44]).
+]
+
+The best way to resolve syntactic errors is for programmers to inspect the code ["by eye] instead of trying to make sense of the compiler errors.
+This section is very useful for programmers to make sure that they are using the syntax correctly.
+
+[section Preprocessor DSEL]
+
+The syntax used by this library macros effectively defies a new language within C++.
+More precisely, this library macros define a [@http://en.wikipedia.org/wiki/Domain-specific_language Domain-Specific Embedded Language (DSEL)] that replaces the usual C++ syntax for class and function declarations.
+This is the ['Language of Contract++] (or ['LC++] for short).
+
+In contrast with other DSEL hosted by C++ which are parsed using template meta-programming (e.g., __Boost_Phoenix__), this library DSEL is parsed ["one meta-programming level higher] using preprocessor meta-programming.
+Using both processor meta-programming and template meta-programming allows this library to implement rules like this:
+
+    ``/if a member function is not public then it does not check the class invariants/``
+
+This rule cannot be implemented using only template meta-programming because it is not possible to check if a function is public using template meta-programming introspection techniques.
+For example, it is not possible to implement a boolean meta-function like the following:
+[footnote
+Using __CXX11__, it /might/ be possible to implement the `is_public` template because __SFINAE__ was extended to support access level (but to the authors' knowledge such a meta-function has not been implemented yet so the authors cannot be sure that `is_public` can be properly implemented even using __CXX11__ __SFINAE__).
+Even if that were possible in __CXX11__, this library still needs declaration traits other than `public` in oder to properly implement Contract Programming (e.g., if a function is `virtual` or not in order to implement subcontracting, and there are examples like that).
+Therefore, the arguments made here for the need to use a preprocessor DSEL in oder to properly implement Contract Programming in C++ hold even if `is_public` could be implemented in __CXX11__.
+]
+
+    template< ... >
+    struct is_public { ... }; // Unfortunately, this cannot be implemented.
+
+Instead a macro can be programmed to parse the following function declarations and expand to `1` if and only if the function is public:
+
+    #define IS_PUBLIC(function_declaration) ... // This can be implemented.
+
+    IS_PUBLIC( public  void (f) ( int x ) )     // Expand to 1.
+    IS_PUBLIC( private void (g) ( int y ) )     // Expand to 0.
+    IS_PUBLIC(         void (h) ( int z ) )     // Expand to 0.
+
+There are more examples of class and function declaration traits (`virtual`, etc) that need to be known to correctly implement Contract Programming but that cannot be inspected using template meta-programming.
+This library macros can instead parse the specified class and function declarations extracting /any/ declaration trait (if a constructor is `explicit`, if a member function is `virtual`, if a base class is `protected`, if a parameter has a default value, etc).
+
+It should be noted that while the syntax of the DSEL defined by this library macros is rather extensive and complex, macros always define a DSEL that is intrinsically different from the core C++ language.
+For example, consider the following function-like macro:
+
+    #define F(x, y) (int(x) - int(y))
+
+    template< typename X, typename Y >
+    int f ( X const& x, Y const& y ) { return (int(x) - int(y)); }
+
+    int main ( void )
+    {
+        std::cout << F( , 2) << std::endl; // OK, no syntax error, it prints `-2`.
+        std::cout << f( , 2) << std::endl; // Compiler generates a syntax error.
+        return 0;
+    }
+
+Note how it is valid to invoke the macro with an empty parameter `F( , 2)` while it is syntactically invalid to invoke a function with an empty parameter `f( , 2)`.
+This very simple macro already shows fundamental differences between the syntax of macros and the syntax of the core language.
+
+[endsect]
+
+[section Differences with C++ Syntax]
+
+The following is a summary of all the differences between the syntax of this library macros and the usual C++ class and function declaration syntax.
+
+[table
+[ [Rule] [Syntactic Element] [Syntax Differences] ]
+[ [1] [Template Declarations] [
+Use round parenthesis `template( `[^['template-parameters]]` )` instead of angular parenthesis `template< `[^['template-parameters]]` >` to declare templates (note that template instantiations are not template declarations and they use angular parenthesis as usual).
+] ]
+[ [2] [Template Specializations] [
+Use round parenthesis `( `[^['template-specializations]]` )` instead of angular parenthesis `< `[^['template-specializations]]` >` after a class template name to specify template specialization arguments.
+] ]
+[ [3] [Class, Function, and Operator Names] [
+Wrap class and function declaration names within round parenthesis `(`[^['class-name]]`)` and `(`[^['function-name]]`)`.
+Use `operator(`[^['symbol]]`)(`[^['arbitrary-name]]`)` for operators (allowed but not required for `operator new`, `operator delete`, and implicit type conversion operators for fundamental types with no symbol).
+Always use `operator comma` for comma operator.
+Memory member operators must always be explicitly declared `static`.
+] ]
+[ [4] [Base Classes] [
+Use `extends( `[^['base-classes]]` )` instead of the column symbol `: `[^['base-classes]] to inherit from base classes.
+] ]
+[ [5] [Default Parameters] [
+Use `default `[^['parameter-default]] instead of the assignment symbol `= `[^['parameter-default]] to specify template and function parameter default values.
+] ]
+[ [6] [Member Access Levels] [
+Always specify the access level `public`, `protected`, or `private` (note no trailing comma `:`) for every constructor, destructor, member function, and nested class declaration.
+] ]
+[ [7] [Result and Parameter Types] [
+Wrap function result and parameter types within round parenthesis `(`[^['type]]`)`.
+The wrapping parenthesis are allowed but not required for fundamental types containing only alphanumeric tokens (e.g., both `(const unsigned int)` and `const unsigned int` are allowed, only `(int&)` and not `int&` is allowed because of the non-alphanumeric symbol `&`, only `(mytype)` is allowed because `mytype` is not a fundamental type).
+] ]
+[ [8] [Member Initializers] [
+Use `initialize( `[^['member-initializers]]` )` instead of the column symbol `: `[^['member-initializers]] to specify constructor member initializers.
+] ]
+[ [9] [Empty Lists] [
+Specify empty lists (parameters, exception specifications, template specializations, etc) using `( void )` instead of `( )` or `< >`.
+] ]
+[ [10] [Commas and Leading Symbols] [
+Syntactic elements containing commas and leading non-alphanumeric symbols must be wrapped within extra round parenthesis `(...)`.
+(Note that `'a'`, `"abc"`, `1.23`, etc are not alphanumeric so they need to be wrapped as `('a')`, `("abc")`, `(1.23)`, etc when specified as default parameters or similar.)
+] ]
+]
+
+[important
+In general, every token which is not a known keyword (`int` is a known keyword but the function name is not) or that contains a non-alphanumeric symbol (e.g., `int&`) must be wrapped within round parenthesis `(...)` unless it is the very last token of a syntactic element (e.g., the function parameter name).
+]
+
+Sometimes the C++ syntax allows to equivalently specify elements in different orders (e.g., `const volatile` and `volatile const` are both allowed for member functions and they have the same meaning).
+The syntax of this library requires instead to specify the elements exactly in the order listed by this grammar (e.g., only `const volatile` is allowed for member functions).
+[footnote
+*Rationale.*
+This library macros could be implemented to allow to specify syntactic elements in different orders but that would complicate the macro implementation and this grammar with no additional feature for the user.
+]

+This is the syntax used to declare all functions: Free functions, member functions, constructors, destructors, and operators.
+The usual constraints of C++ function declarations apply: It is not possible to declare a static virtual member function, only constructors can use the class name as the function name, constructors and destructors have no result type, etc.
+The `static` specifier can only be used for member functions (because it was deprecated for free functions from C to __CXX03__).
+The `volatile` specifier must always appear after `const` when they are both specified.

+            operator new ``/|/`` operator delete ``/|/`` operator comma
+
+Names for free functions, member functions, constructors, and destructors are specified as usual but wrapped within parenthesis.
+
+Operator names are specified wrapping within parenthesis the usual operator symbol followed by an arbitrary but alphanumeric identifier:
+
+    operator([])(at)
+    operator(+)(plus)
+    operator(())(call)
+    operator(new[])(new_array)
+    operator(delete[])(delete_array)
+
+Implicit type conversion operators use the same syntax:
+
+    operator(int*)(int_ptr)
+    operator(mytype const&)(mytype_const_ref)
+    operator(std::map<char, int>)(std_map)
+
+However, if the type is a fundamental type containing no symbol, the identifier is optional:
+
+    operator(const int)(const_int)  // Allowed but...
+    operator const int              // ... more readable.
+
+Similarly, the parenthesis and identifier are optional for the `new` and `delete` operators:
+
+    operator(new)(new_ptr)          // Allowed but...
+    operator new                    // ... more readable.
+
+    operator(delete)(delete_ptr)    // Allowed but...
+    operator delete                 // ... more readable.
+
+Finally, the comma symbol `,` cannot be used to specify the comma operator
+[footnote
+*Rationale.*
+Within macros a comma `,` has the special meaning of separating the macro parameters so it cannot be used to indicate the comma operator otherwise `operator(,)(mycomma)` and `operator(std::map<char, int>)(stdmap)` could not be distinguished from one another by the preprocessor.
+]
+so the specifier `comma` must always be used to name the comma operator:
+
+    operator comma      // OK.
+    operator(,)(comma)  // Error.
+
+C++ automatically promotes the memory member operators `operator new`, `operator delete`, `operator new[]`, and `operator delete[]` to be static members so the `static` specifier is allowed but optional for these member operators.
+This library cannot automatically perform such a promotion so the `static` specifier is always required by this library for the memory member operators.

+
+Note that the syntax `throw( void )` is used instead of `throw( )` for no-throw specifications.
+
+Exception specifications apply only to exceptions thrown by the function body and not to exceptions thrown by the contracts themselves (if any) and by the contract checking code generated by this library macros.

+            ``/{/``catch(__catch_declaration__) ( __catch_instructions__ )``/}*/``
+    
+As indicated by this syntax, it is possible to specify function-try blocks for constructor member initializers:
+
+    struct vector_error { ... };
+
+    CONTRACT_CONSTRUCTOR( // Constructor with member initializers.
+    explicit (vector) ( int count )
+        precondition( count >= 0 )
+        postcondition( size() == count )
+
+        try initialize( ptr_(new T[count]) )
+        catch(std::bad_alloc& ex) (
+            std::cerr << "not enough memory for " << count << " elements vector: " << ex.what() << std::endl;
+            throw vector_error(1);
+        ) catch(std::exception& ex) (
+            std::cerr << "error for " << count << " elements vector: " << ex.what() << std::endl;
+            throw vector_error(2);
+        ) catch(...) (
+            std::cerr << "unknown error for " << count << " elements vector" << std::endl;
+            throw vector_error(3);
+        )
+    ) { // Above function-try block only applies to exceptions thrown by the body (and not by the contracts).
+        ...
+    }
+
+For functions other than constructors and for constructors without member initializers, function-try blocks are programmed outside the macros and around the body definition as usual.
+As specified by __N1962__, function-try blocks apply only to exceptions thrown by the function body and not to exceptions thrown by the contracts themselves (if any) and by the contract checking code generated by the library macros.
+
+Member initializers (and their function-try blocks) are part of the constructor definition and not of the constructor declaration.
+However, __CXX03__ lack of delegating constructors requires member initializers (and their function-try blocks) to be specified within this library macros and constructors must be defined together with their declarations when they use member initializers.

+            ``/{/``auto ``/|/`` __wrapped_type__``/}/`` __variable_name__ = ``[macroref CONTRACT_OLDOF]`` __oldof_expression__
+
+If present, result and old-of declarations should appear at the very beginning of the postconditions because they will always be visible to all assertions plus these declarations cannot be nested (within select-assertions, etc).
+
+The result declaration type is always `auto` because the function result type is know and already specified by the function declaration (so no result type deduction is ever needed).
+The old-of declaration type is automatically deduced (using __Boost_Typeof__) when its type is specified `auto` instead of __wrapped_type__.
+The macro `CONTRACT_OLDOF` does not require but allows parenthesis around the value expression __oldof_expression__ (this is as specified for the `oldof` operator in __N1962__ and similar to the `sizeof` operator which requires parenthesis when applied to a type expression `sizeof(size_type)` but not when applied to a value expression `sizeof size()`).
+For example, all the followings are valid:
+
+    auto old_size = CONTRACT_OLDOF size()
+    auto old_size = CONTRACT_OLDOF(size())          // Extra parenthesis around expression (optional).
+    (size_type) old_size = CONTRACT_OLDOF size()    // Do not use Boost.Typeof.
+    (size_type) old_size = CONTRACT_OLDOF(size())   // No Boost.Typeof and extra parenthesis.
+
+If an old-of copy is performed on a type that is not __ConstantCopyConstructible__, the old-of declaration itself will not fail compilation but it will produce an old variable that will cause a compiler-error as soon as it is used in an assertion (unless the assertion specifies a requirement using a properly specialized [classref contract::has_oldof] trait).

+
+Some basic name manipulations are allowed at the local scope where the assertions are being declared in case they are ever needed to simplify the assertion expressions.
+Specifically, using-directives, namespace-aliases, and type-definitions are allowed (these will always affect all assertions within the given preconditions, postconditions, etc so it is recommended to always use these statement at the very beginning before the actual assertion conditions).
+Note that these name manipulations have no effect on the program run-time state and therefore they do not compromise the contract constant-correctness requirement.
+
+As indicated by the grammar above, it is not possible to specify assertion requirements (using `requires`) for the entire select assertion if-then-else expression.
+Eventual assertion requirements must be specified for the single assertions within the select assertion if-then-else statement and they will never disable compilation and checking of the select assertion if-condition.
+Programmers can use the ternary operator `?:` instead of a select assertion if they need to specify a guarded assertion with a condition that is also disabled by the assertion requirements:
+
+    ``/boolean-guard/`` ? __boolean_expression__ : true, requires __constant_boolean_expression__
+
+Constant expressions `const( ... ) `[^['expression]] can be used to assert conditions and to check the select assertion if-condition so to fully enforce the assertion constant-correctness requirement.
+However, function arguments, result value, old-of values, and the object `this` are automatically made constant by this library so constant expressions only need to be used to assert conditions on global variables, static variables, etc.
+The type of the in-scope variable __inscope_variable__ is optional and it is automatically deduced using __Boost_Typeof__ when it is not specified.

+The loop variant can be specified using a constant-expression `const( ... ) `[^['expression]] so to fully enforce the contract constant-correctness requirement.

+If terminals contain commas not already wrapped by round parenthesis or if they start with a non-alphanumeric symbol (including tokens like `'a'`, `"abc"`, `-123`, and `1.23`),
+[footnote
+The C++ preprocessor cannot concatenate `1.23` because it contains the `.` symbol (even if that symbol is technically not the leading symbol).
+The precise preprocessor requirement is that the concatenated symbol must be a valid macro identifier and concatenating `1.23` with any token will never give a valid macro identifier because of the presence of the dot symbol `.` (e.g., `BOOST_PP_CAT(XYZ, 1.23)` gives `XYZ1.23` which is not a valid macro identifier).
+]
+they need to be wrapped by extra round parenthesis `(...)` or by the __Boost_Utility_IdentityType__ `BOOST_IDENTITY_TYPE((...))` macro.
+Value expressions can always be wrapped within extra around parenthesis in C++.
+Type expressions can always be wrapped using __Boost_Utility_IdentityType__ but that will make the syntax less readable (and it prevents C++ from automatically deducing function template parameters) so this syntax allows to wrap type expressions within extra round parenthesis `(...)` for most terminals, including types, as indicated by the table above.

+[section Alternative Assertion Syntax (Not Implemented)]
+
+The following alternative syntax could have been implemented to program the contract assertions:
+
+[table
+[ [This Library Syntax] [Alternative Syntax (not implemented)] ]
+[ [``
+CONTRACT_CLASS(
+    template( typename T )
+    class (vector)
+) {
+    ...
+
+    CONTRACT_FUNCTION_TPL(
+        public (iterator) (erase) ( (iterator) where )
+            precondition(
+                not empty(),
+                where != end(),
+                static_assert(sizeof(T) >= sizeof(int), "large enough")
+            )
+            postcondition(
+                auto result = return,
+                auto old_size = CONTRACT_OLDOF size(),
+                size() == old_size - 1,
+                if(const( this ) this->empty()) (
+                    result == end()
+                )
+            )
+    ) {
+        return vector_.erase(where);
+    }
+};
+`` ] [``
+CONTRACT_CLASS(
+    template( typename T )
+    class (vector)
+) {
+    ...
+
+    CONTRACT_FUNCTION_TPL(
+        public (iterator) (erase) ( (iterator) where )
+            precondition(
+                assert(not empty())
+                assert(where != end())
+                static_assert(sizeof(T) >= sizeof(int), "large enough")
+            )
+            postcondition(
+                decl(auto result = return)
+                decl(auto old_size = CONTRACT_OLDOF size())
+                assert(size() == old_size - 1)
+                if(const(this, this->empty())) (
+                    assert(result == end())
+                )
+            )
+    ) {
+        return vector_.erase(where);
+    }
+};
+``] ]
+]
+
+An advantage of this alternative syntax is that it does not require commas at the end of each assertion.
+However, when compared with this library syntax, the alternative syntax is overall more verbose, it uses more parenthesis, it deviates more from __N1962__ and __Eiffel__ (even if it is more similar to __D__), and it looks less readable at least because of `decl(...)` (in many ways this alternative syntax is equivalent to the already supported sequencing syntax from the __No_Variadic_Macros__ section with the addition of ["decoration identifiers] like `assert` which might make the code more readable but are not needed syntactically).
+Therefore, the authors opted for implementing the syntax on the left hand side.

Therefore, preconditions can only be specified by functions at the very root of the inheritance tree and they cannot be subcontracted (this is as specified by  <a class="link" href="contract__/bibliography.html" title="Bibliography"> [N1962]</a>, however note that in case of multiple-inheritance the preconditions of all base functions will still be checked in logic-or with each other effectively still allowing a base class to weaken the preconditions from another base class).</p>

+<a name="id1046941"></a><h2>Description</h2>
+<p>This macro is used to declare a constructor with possible preconditions and postconditions. At least all public constructors of a class with non-empty class invariants should be declared using this macro so to check the class invariants (even if the constructors have no precondition and no postcondition).</p>
+<p>The semantics of a call to a constructor with contracts are explained in the  <a class="link" href="contract__/contract_programming_overview.html" title="Contract Programming Overview"> Contract Programming Overview</a> section. Destructors and member functions are declared using the  <code class="computeroutput"><a class="link" href="CONTRACT_DESTRUCTOR.html" title="Macro CONTRACT_DESTRUCTOR">CONTRACT_DESTRUCTOR</a></code> and  <code class="computeroutput"><a class="link" href="CONTRACT_FUNCTION.html" title="Macro CONTRACT_FUNCTION">CONTRACT_FUNCTION</a></code> macros respectively.</p>

+<td>The constructor declaration syntax is explained in the  <a class="link" href="contract__/grammar.html" title="Grammar"> Grammar</a> section. Constructors must always repeat their access level <code class="computeroutput">public</code>, <code class="computeroutput">protected</code>, or <code class="computeroutput">private</code>. If present, member initializers must be specified using <code class="computeroutput">initialize( ... )</code> and within this macro (even if they are technically part of the constructor definition and not of its declaration).  </td>

+</table></div>
+<p>
+</p>
+<p>The  <code class="computeroutput"><a class="link" href="CONTRACT_CLASS.html" title="Macro CONTRACT_CLASS">CONTRACT_CLASS</a></code> macro must be used to declare the class enclosing a constructor declared using this macro.</p>
+<p>Within a type-dependent scope (e.g., within templates), the  <code class="computeroutput"><a class="link" href="CONTRACT_CONSTRUCTOR_TPL.html" title="Macro CONTRACT_CONSTRUCTOR_TPL">CONTRACT_CONSTRUCTOR_TPL</a></code> macro must be used instead of this macro.</p>
+<p>The  <code class="computeroutput"><a class="link" href="CONTRACT_CONSTRUCTOR_BODY.html" title="Macro CONTRACT_CONSTRUCTOR_BODY">CONTRACT_CONSTRUCTOR_BODY</a></code> macro must be used when separating the constructor body definition form the constructor declaration programmed using this macro. Unfortunately, it is not possible to use this macro so separate body definitions for constructors that have member initializers.</p>

+<p>This macro refers the old value of the expression that follows the macro (i.e., the value the expression had after function entry but before body execution).

+</pre>
+<p>The specified expression that follows the macro might or not be wrapped within parenthesis.</p>
+<p>The old-of expression type can be explicitly specified instead of <code class="computeroutput">auto</code> but it must be wrapped within parenthesis unless it is a fundamental type containing no symbol. If not explicitly specified, the library will automatically deduce the type using Boost.Typeof (as always, types must be properly registered with Boost.Typeof for type-of emulation mode on compilers that do not support native type-of).</p>

+<a name="id1043225"></a><h2>Description</h2>
+<p>This exception contains detailed information about the failed contract assertion (file name, line number, etc).</p>
+<p>A contract assertion is considered failed if it cannot be evaluated to be true (so if it is evaluated to be false but also if an exception is thrown by the code that evaluates the assertion condition). In case a contract assertion fails, the library automatically calls the appropriate contract broken handler with this exception as the active exception (the fact that assertion failures are signaled by this library by throwing this exception does not necessarily mean that the exception will be ultimately thrown by the broken contract, that is entirely up to the implementation of the contract broken handlers). By default, contract broken handlers print an error message to <code class="computeroutput">std::cerr</code> and terminate the program calling <code class="computeroutput">std::terminate</code>, but programmers can redefine this behaviour by customizing the contract broken handlers (for example to have the handlers throw exceptions instead of terminating the program). Within customized contract broken
 handlers, programmers can re-throw and catch this exception to obtained information about the failed asserted condition (file name, line number, etc).</p>
+<p><span class="bold"><strong>Note:</strong></span> This exception is guaranteed to publicly inherit from <code class="computeroutput">std::logic_error</code> (because <code class="computeroutput">std::logic_error</code> models programming errors and those are the type of errors that contract assertions detect).</p>

+<p>A type can be used for a postcondition old value if and only if it can be copied using the  <code class="computeroutput"><a class="link" href="copy.html" title="Class template copy">contract::copy</a></code> template. By default, all types that have a constant-correct copy constructor (i.e., that are <code class="computeroutput">ConstantCopyConstructible</code>) can be copied by  <code class="computeroutput"><a class="link" href="copy.html" title="Class template copy">contract::copy</a></code>.</p>
+<p>If a type cannot be copied, an old value declaration using such a type will not fail but it will generate an old value that will cause a compile-time error as soon as it is used in a contract assertion. Therefore, this trait can be used to program assertion requirements for those assertions that use old values on generic types that are not always known to be copyable. This way, the assertions will be disabled by the requirement instead of generating a compile-time error when the old values they use cannot be copied.</p>

+</tr></tbody>
+</table></div>
+<p>
+</p>
+<p>Unfortunately, in C++ it is not possible to portably implement a template meta-function that checks if a generic type has a constant-correct copy constructor (or even just a copy constructor). Therefore, the default implementation of this trait is <code class="computeroutput">boost::mpl::true_</code> for any type <code class="computeroutput">OdlofExpressionType</code>. This will cause compile-time errors for old value types that cannot be copied in which case users can specialize this unary boolean meta-function to inherit from <code class="computeroutput">boost::mpl::false_</code> for such types.</p>

+        C++ macros cannot correctly parse a macro parameter if it contains a comma
+        <code class="computeroutput"><span class="special">,</span></code> that is not wrapped within
+        round parenthesis <code class="computeroutput"><span class="special">()</span></code> (because
+        the preprocessor interprets such a comma as separation between two distinct
+        macro parameters instead that as part of one single macro parameter, see
+        also Boost.Utility/IdentityType).
+        Furthermore, syntactic elements specified to this library macros cannot start
+        with a non-alphanumeric symbol (<code class="computeroutput"><span class="special">-</span><span class="number">1</span></code>, <code class="computeroutput"><span class="number">1.23</span></code>,
+        <code class="computeroutput"><span class="string">"abc"</span></code>, <code class="computeroutput"><span class="special">::</span></code>, etc). <sup>[<a name="contract__.advanced_topics.commas_and_leading_symbols_in_macros.f0" href="#ftn.contract__.advanced_topics.commas_and_leading_symbols_in_macros.f0" class="footnote">35</a>]</sup> For example, the parameter type <code class="computeroutput"><span class="special">::</span><span class="identifier">std</span><span class="special">::</span><span class="identifier">pair</span><span class="special">&lt;</span><span class="identifier">OtherKey</span><span class="special">,</span> <span class="identifier">OtherT</span><span class="special">&gt;</span> <span class="keyword">const</span><span class="special">&amp;</span></code> cannot be passed to this library for
+        two reasons: It starts with the non-alphanumeric symbol <code class="computeroutput"><span class="special">::</span></code>
+        and it contains the comma <code class="computeroutput"><span class="identifier">OtherKey</span><span class="special">,</span> <span class="identifier">OtherT</span></code>
+        which is not wrapped by round parenthesis.
+      </p>
+<p>
+        The Boost.Utility/IdentityType
+        macro <code class="computeroutput"><span class="identifier">BOOST_IDENTITY_TYPE</span></code>
+        can be used as usual to overcome this issue. However, using the <code class="computeroutput"><span class="identifier">BOOST_IDENTITY_TYPE</span></code> macro presents two
+        limitations: It makes the syntax of this library macros more cumbersome and,
+        more importantly, it does not allow C++ to automatically deduce function
+        template parameters (see Boost.Utility/IdentityType
+        for more information). Therefore, the syntax of this library provides an
+        alternative to <code class="computeroutput"><span class="identifier">BOOST_IDENTITY_TYPE</span></code>
+        to handle commas and leading symbols within macro parameters:
+      </p>

+<li class="listitem">
+            Commas and leading symbols can be used freely within elements of the

+        Static assertions are always checked at compile-time (regardless of them
+        appearing in preconditions, postconditions, etc). However, static assertions
+        can be selectively disabled depending on where they are specified using

+        features). It is recommended to always specify meaningful messages for static
+        assertions to increase the readability and documentation of contracts. Similarly,
+        it might be useful to put a short code comment following each assertions
+        (<code class="computeroutput"><span class="comment">// pointer not null</span></code>, etc) to
+        increase contract readability and documentation. <sup>[<a name="contract__.advanced_topics.static_assertions.f0" href="#ftn.contract__.advanced_topics.static_assertions.f0" class="footnote">37</a>]</sup>

+        Only assertions can be programmed within the contracts while normal C++ statements
+        are not allowed. This is keeps contracts simple making programming errors

+<p>
+        In general, programming contract assertions can introduce a new set of requirements
+        on the types used by the program. Some of these type requirements might be
+        necessary only to program the assertions and they might not be required by
+        the implementation itself. In such cases, if the code is compiled with contracts
+        disabled (<code class="computeroutput"><a class="link" href="../CONTRACT_CONFIG_NO_PRECONDITIONS.html" title="Macro CONTRACT_CONFIG_NO_PRECONDITIONS">CONTRACT_CONFIG_NO_PRECONDITIONS</a></code>,
+        etc), the program might compile but it might no longer compile when contracts
+        are enabled because some of the types do not provide all the operations necessary
+        to check the contract assertions.
+      </p>
+<div class="orderedlist"><ol class="orderedlist" type="1">
+<li class="listitem">
+            More in general, in some cases it might be acceptable or even desirable
+            to cause a compile-time error when a program uses types that do not provide
+            all the operations needed to check the contracts (because it is not possible
+            to fully check the correctness of the program). In these cases, programmers
+            specify contract assertions as we have seen so far (and maybe even use
+            concepts to explicitly specify the contract type requirements, see the
+            <a class="link" href="concepts.html" title="Concepts">Concepts</a> section).
+          </li>
+<li class="listitem">
+            However, in other cases it might be desirable that adding contracts to
+            a program does not change its type requirements and that assertions are
+            simply not checked when the types do not provide all the operations necessary
+            to evaluate the asserted conditions. In these cases, programmers can

+</pre>
+<p>
+        (The constant boolean expression of an assertion requirement can be wrapped
+        within round parenthesis <code class="computeroutput"><span class="special">()</span></code>
+        if it contains unwrapped commas.)
+      </p>
+<p>
+        Let's consider the STL <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">vector</span><span class="special">&lt;</span><span class="identifier">T</span><span class="special">&gt;</span></code>
+        class template. This template normally does not require the value type <code class="computeroutput"><span class="identifier">T</span></code> to be EqualityComparable
+        (i.e., to have an equality operator <code class="computeroutput"><span class="special">==</span></code>),
+        it only requires <code class="computeroutput"><span class="identifier">T</span></code> to be
+        CopyConstructible
+        (i.e., to have a copy constructor). However, in order to check the following
+        <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">vector</span><span class="special">&lt;</span><span class="identifier">T</span><span class="special">&gt;::</span><span class="identifier">push_back</span></code> postcondition:

+<pre class="programlisting"><span class="identifier">back</span><span class="special">()</span> <span class="special">==</span> <span class="identifier">value</span> <span class="comment">// Compiler error if not `EqualityComparable&lt;T&gt;`.</span>
+</pre>
+<p>
+        The type <code class="computeroutput"><span class="identifier">T</span></code> must to be EqualityComparable.
+        Therefore, the EqualityComparable
+        requirement on <code class="computeroutput"><span class="identifier">T</span></code> is introduced
+        only by the contract assertions and it is not required by the <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">vector</span><span class="special">&lt;</span><span class="identifier">T</span><span class="special">&gt;</span></code>
+        implementation.
+      </p>
+<p>
+        In some cases, programmers might want compilation to fail when <code class="computeroutput"><span class="identifier">T</span></code> is not EqualityComparable
+        because in these cases it is not possible to fully check the <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">vector</span><span class="special">&lt;</span><span class="identifier">T</span><span class="special">&gt;</span></code>
+        contract and therefore its correctness (in these cases programmers do not
+        specify assertion requirements and let the compilation fail, or even better
+        programmers can explicitly specify the assertion type requirements using
+        concepts which will also fail compilation but hopefully with more informative
+        error messages, see the <a class="link" href="concepts.html" title="Concepts">Concepts</a>
+        section).
+      </p>
+<p>
+        However, in other cases programmers might want to use the contracted version
+        of <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">vector</span><span class="special">&lt;</span><span class="identifier">T</span><span class="special">&gt;</span></code> exactly
+        as they use the non-contracted version of the template and therefore without
+        failing compilation if <code class="computeroutput"><span class="identifier">T</span></code>
+        is not EqualityComparable.
+        This can be achieved specifying assertion requirements for the <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">vector</span><span class="special">&lt;</span><span class="identifier">T</span><span class="special">&gt;::</span><span class="identifier">push_back</span></code> postcondition:

+        The Boost.TypeTraits
+        library provides a set of meta-functions that are very useful to program
+        assertion requirements. <sup>[<a name="contract__.advanced_topics.assertion_requirements.f3" href="#ftn.contract__.advanced_topics.assertion_requirements.f3" class="footnote">43</a>]</sup> However, C++ does not allow to inspect every trait of a type
+        so there might be some assertion requirements that unfortunately cannot be
+        programmed within the language.
+      </p>
+<p>
+        Another interesting use of assertion requirements is to model assertion computational
+        complexity. In some cases, checking assertions can be as computationally
+        expensive as executing the function body or even more. While preconditions,
+        postconditions, etc can be disabled in groups at compile-time to improve
+        performance (using <code class="computeroutput"><a class="link" href="../CONTRACT_CONFIG_NO_PRECONDITIONS.html" title="Macro CONTRACT_CONFIG_NO_PRECONDITIONS">CONTRACT_CONFIG_NO_PRECONDITIONS</a></code>,
+        <code class="computeroutput"><a class="link" href="../CONTRACT_CONFIG_NO_POSTCONDITIONS.html" title="Macro CONTRACT_CONFIG_NO_POSTCONDITIONS">CONTRACT_CONFIG_NO_POSTCONDITIONS</a></code>,
+        etc), it is also useful to be able to disable only specific assertions that
+        are very computationally expensive while keeping all other preconditions,
+        postconditions, etc enabled. For example (see also assertion_complexity_factorial.cpp):

+        While subcontracting is theoretically sound and justified by the <a href="http://en.wikipedia.org/wiki/Liskov_substitution_principle" target="_top">substitution
+        principle</a>, in practise subcontracted preconditions might be confusing
+        for programmers because of the implications of evaluating overriding preconditions
+        in <a class="link" href="contract_programming_overview.html#logic_or_anchor">logic-or</a> with overridden preconditions
+        (this is not the case for subcontracted postconditions and class invariants
+        which usually behave as programmers expect because they are evaluated in

+      </p>
+<p>
+        For example, consider the following base class <code class="computeroutput"><span class="identifier">integer</span></code>
+        which holds an integral value and its derived class <code class="computeroutput"><span class="identifier">natural</span></code>
+        which holds a natural (i.e., non-negative integer) value (see also subcontract_pre_natural_failure.cpp):

+<p>
+        This last conclusion is incorrect! Negative values can be passed to <code class="computeroutput"><span class="identifier">natural</span><span class="special">::</span><span class="identifier">set</span></code> because they can be passed to its base

+        is given by its base virtual function <code class="computeroutput"><span class="identifier">integer</span><span class="special">::</span><span class="identifier">set</span></code> preconditions

+        <code class="computeroutput"><span class="identifier">value</span> <span class="special">&gt;=</span>

+<p>
+        Obviously, this always evaluates to <code class="computeroutput"><span class="keyword">true</span></code>
+        regardless of <code class="computeroutput"><span class="identifier">value</span></code> being
+        non-negative. This is correct in accordance with the <a href="http://en.wikipedia.org/wiki/Liskov_substitution_principle" target="_top">substitution
+        principle</a> for which <code class="computeroutput"><span class="identifier">natural</span><span class="special">::</span><span class="identifier">set</span></code> can
+        be called in any context where <code class="computeroutput"><span class="identifier">integer</span><span class="special">::</span><span class="identifier">set</span></code> is
+        called because <code class="computeroutput"><span class="identifier">natural</span></code> inherits
+        from <code class="computeroutput"><span class="identifier">integer</span></code>. Given that
+        <code class="computeroutput"><span class="identifier">integer</span><span class="special">::</span><span class="identifier">set</span></code> can be called regardless of <code class="computeroutput"><span class="identifier">value</span></code> being non-negative (because it has

+        <code class="computeroutput"><span class="identifier">natural</span><span class="special">::</span><span class="identifier">set</span></code> that will change that and in fact
+        <code class="computeroutput"><span class="identifier">natural</span><span class="special">::</span><span class="identifier">set</span></code> can also be called with negative values
+        without failing its subcontracted preconditions. For example, the call:
+      </p>
+<p>

+<pre class="programlisting"><span class="identifier">natural</span> <span class="identifier">n</span><span class="special">;</span>

+<pre class="programlisting">class invariant (on exit) number 1 "get() &gt;= 0" failed: file "natural_subcontractpre.cpp", line 30
+</pre>
+<p>
+        Ideally, this call would have failed much earlier at <code class="computeroutput"><span class="identifier">natural</span><span class="special">::</span><span class="identifier">set</span></code> preconditions
+        (in fact, the <code class="computeroutput"><span class="identifier">natural</span><span class="special">::</span><span class="identifier">set</span></code> body is executed with the logically
+        invalid negative value <code class="computeroutput"><span class="special">-</span><span class="number">123</span></code>
+        which could in general lead to catastrophic errors and mysterious bugs).
+      </p>
+<p>
+        The issue here is in the design. A natural number is not an integer number
+        because while it is valid to use an integer number in a context where it
+        is assigned to a negative number, it is not valid to use a natural number
+        in such a context so a natural number should not inherit from an integer
+        number. Inheritance models the is-a
+        relationship which should not be used in this case as the contracts and the
+        <a href="http://en.wikipedia.org/wiki/Liskov_substitution_principle" target="_top">substitution
+        principle</a> are telling us.

+          Note that if a virtual member function has no preconditions, it means that

+          principle</a>) this semantic cannot be changed by the contracts of
+          any overriding function no matter what preconditions we specify for it.
+          Similarly, if an overriding member function has no preconditions, it means
+          that is is always valid to call it regardless of possible preconditions
+          specified by any function that it overrides.
+        </p></td></tr>
+</table></div>
+<p>
+        An overriding function can specify <code class="computeroutput"><span class="identifier">precondition</span><span class="special">(</span> <span class="keyword">false</span> <span class="special">)</span></code>
+        if it wants to keep the same preconditions of the functions that is overriding.
+        A pure virtual function can specify <code class="computeroutput"><span class="identifier">precondition</span><span class="special">(</span> <span class="keyword">false</span> <span class="special">)</span></code>
+        to indicate that overriding functions will specify preconditions (this only
+        makes sense for pure virtual functions because a function with <code class="computeroutput"><span class="identifier">precondition</span><span class="special">(</span>
+        <span class="keyword">false</span> <span class="special">)</span></code>
+        can never be called successfully unless it is overridden and its preconditions
+        are weakened, that might be acceptable for pure virtual because they must
+        always be overridden).
+      </p>
+<p>
+        If programmers find subcontracted preconditions confusing, this library allows
+        to forbid them by defining the configuration macro <code class="computeroutput"><a class="link" href="../CONTRACT_CONFIG_DO_NOT_SUBCONTRACT_PRECONDITIONS.html" title="Macro CONTRACT_CONFIG_DO_NOT_SUBCONTRACT_PRECONDITIONS">CONTRACT_CONFIG_DO_NOT_SUBCONTRACT_PRECONDITIONS</a></code>.
+        When this macro if defined, the library will generate a compile-time error
+        if a derived class tries to override preconditions of member functions of
+        any of its base classes (this is also the subcontracting behaviour specified
+        by <a class="link" href="bibliography.html#N1962_anchor">[N1962]</a>). However, note that in case
+        of multiple-inheritance preconditions from the overridden function from all
+        bases classes will always be checked in <a class="link" href="contract_programming_overview.html#logic_or_anchor">logic-or</a>
+        with each other so preconditions from a base class could still be weaken
+        by the preconditions of another base class even when the <code class="computeroutput"><a class="link" href="../CONTRACT_CONFIG_DO_NOT_SUBCONTRACT_PRECONDITIONS.html" title="Macro CONTRACT_CONFIG_DO_NOT_SUBCONTRACT_PRECONDITIONS">CONTRACT_CONFIG_DO_NOT_SUBCONTRACT_PRECONDITIONS</a></code>
+        macro is defined. By default the <code class="computeroutput"><a class="link" href="../CONTRACT_CONFIG_DO_NOT_SUBCONTRACT_PRECONDITIONS.html" title="Macro CONTRACT_CONFIG_DO_NOT_SUBCONTRACT_PRECONDITIONS">CONTRACT_CONFIG_DO_NOT_SUBCONTRACT_PRECONDITIONS</a></code>
+        macro is not defined and this library allows to override preconditions (as
+        specified by for Eiffel
+        by <a class="link" href="bibliography.html#Meyer97_anchor">[Meyer97]</a> and in accordance with
+        the <a href="http://en.wikipedia.org/wiki/Liskov_substitution_principle" target="_top">substitution
+        principle</a>).
+      </p>
+<p>
+        Another difference between subcontracted preconditions and subcontracted
+        postconditions or class invariants is that subcontracted preconditions will
+        always report a failure of the overridden preconditions. For example, consider
+        a set of base classes <code class="literal">b<span class="emphasis"><em>N</em></span></code> and a derived

+<p>
+        It is possible to program exception specifications and function-try blocks
+        for constructors, destructors, member functions, and free functions with
+        contracts. Exception specifications are part of the function declarations
+        therefore they are programmed within the contract macros but the special
+        syntax <code class="computeroutput"><span class="keyword">throw</span><span class="special">(</span>
+        <span class="keyword">void</span> <span class="special">)</span></code>
+        must be used instead of <code class="computeroutput"><span class="keyword">throw</span><span class="special">(</span> <span class="special">)</span></code> to specify
+        that no exception is thrown:
+      </p>
+<pre class="programlisting"><span class="keyword">throw</span><span class="special">(</span> <span class="emphasis"><em>exception-type1</em></span><span class="special">,</span> <span class="emphasis"><em>exception-type2</em></span><span class="special">,</span> <span class="special">...</span> <span class="special">)</span> <span class="comment">// As usual.</span>

+</pre>
+<p>
+        Function-try blocks are part of the function definition so they are normally
+        programmed outside the contract macros. However, for constructors with member
+        initializers, the member initializers must be programmed within the <code class="computeroutput"><a class="link" href="../CONTRACT_CONSTRUCTOR.html" title="Macro CONTRACT_CONSTRUCTOR">CONTRACT_CONSTRUCTOR</a></code> macro and therefore
+        also the function-try blocks must be programmed within the macro using the
+        following syntax:

+</pre>
+<p>
+        As usual, only one catch statement must be specified and the other catch
+        statements are optional plus <code class="computeroutput"><span class="keyword">catch</span><span class="special">(...)</span></code> can be used to catch all exceptions.
+        Note however that round parenthesis <code class="computeroutput"><span class="special">(</span>
+        <span class="special">...</span> <span class="special">)</span></code>
+        are used instead of curly parenthesis <code class="computeroutput"><span class="special">{</span>
+        <span class="special">...</span> <span class="special">}</span></code>
+        to wrap the catch statement instructions (then the catch instructions are
+        programmed with the usual syntax and separated by semicolons <code class="computeroutput"><span class="special">;</span></code>). (The maximum number of catch statements
+        that can be programmed for constructor-try blocks is specified by the <code class="computeroutput"><a class="link" href="../CONTRACT_LIMIT_CONSTRUCTOR_TRY_BLOCK_CATCHES.html" title="Macro CONTRACT_LIMIT_CONSTRUCTOR_TRY_BLOCK_CATCHES">CONTRACT_LIMIT_CONSTRUCTOR_TRY_BLOCK_CATCHES</a></code>
+        macro.)
+      </p>
+<p>
+        In the following example the constructor uses a function-try block to throw
+        only <code class="computeroutput"><span class="identifier">out_of_memory</span></code> and <code class="computeroutput"><span class="identifier">error</span></code> exceptions while the destructor uses

+        They are programmed specifying a list of assertions to the <code class="computeroutput"><a class="link" href="../CONTRACT_BLOCK_INVARIANT.html" title="Macro CONTRACT_BLOCK_INVARIANT">CONTRACT_BLOCK_INVARIANT</a></code>

+        When block invariants are used within a loop, they are also called <span class="emphasis"><em>loop

+        uses this terminology).
+      </p>
+<p>
+        Furthermore, this library allows to specify <a href="http://en.wikipedia.org/wiki/Loop_variant" target="_top"><span class="emphasis"><em>loop
+        variants</em></span></a>. A loop variant is a non-negative monotonically
+        decreasing number that is updated at each iteration of the loop. The specified
+        loop variant expression is calculated by this library at each iteration of
+        the loop and it is automatically asserted to be non-negative (<code class="computeroutput"><span class="special">&gt;=</span> <span class="number">0</span></code>) and
+        to decrease monotonically from the previous loop iteration. Because the loop
+        variant monotonically decreases and it cannot be smaller than zero, either

+        <code class="computeroutput"><span class="keyword">for</span></code>, <code class="computeroutput"><span class="keyword">do</span></code>,

+<p>
+        Note that the library cannot automatically make constant any of the variables

+        When a contract assertion fails, this library prints a message on the standard
+        error <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">cerr</span></code> and it terminates the program calling
+        <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">terminate</span></code>. Programmers can change this
+        behavior customizing the actions that the library takes on contract assertion
+        failure by setting the contract broken handler functions. By default the
+        library terminates the program because a contract failure indicates that
+        the program is in an invalid state that programmers specified it should never
+        happen (so the only sensible assumption is that the program execution should
+        not continue). However, in some cases programmers might need to handle even
+        such catastrophic failures by executing some fail-safe code instead of terminating
+        the program and that can be done customizing the contract broken handlers.

+        is equivalent to setting all these class invariant broken handles to the

+              class invariant number <code class="computeroutput"><span class="number">2</span></code>
+              failed. Therefore, the assertion number is not useful if a single handler
+              is programmed for all types of contracts because such an handler can
+              no longer distinguish between class invariants, preconditions, postconditions,
+              etc.

+          <span class="bold"><strong>Rationale.</strong></span> Threating an exception thrown
+          while evaluating an assertion as a failure of the contract assertion is
+          a clear policy established by this library under the principle that a contract
+          assertion fails unless it is evaluated to be true. <a class="link" href="bibliography.html#N1962_anchor">[N1962]</a>
+          does not completely clarify this point.

+          In this example, contract failures from destructors are logged and then
+          simply ignored. That might be acceptable in this simple example but it
+          is probably a very bad idea in general.

+      This section explains how to use this library to check concepts. Concepts are
+      part of the program specifications because they enforce requirements on generic
+      types at compile-time and therefore they are within the scope of this library.
+    </p>
+<p>
+      Concepts were proposed for addition to C++11
+      but they were unfortunately never adopted (see <a class="link" href="bibliography.html#N2081_anchor">[N2081]</a>).
+      The concepts that are checked using this library need to be defined using the
+      Boost.ConceptCheck
+      library. This library does not add any extra functionality with respect to
+      the concept checking features already provided by Boost.ConceptCheck
+      but it allows to specify both concepts and contracts together within a unified
+      syntax.
+    </p>
+<div class="section">
+<div class="titlepage"><div><div><h3 class="title">
+<a name="contract__.concepts.class_templates"></a><a class="link" href="concepts.html#contract__.concepts.class_templates" title="Class Templates">Class Templates</a>
+</h3></div></div></div>
+<p>
+        It is possible to list the concepts to check for class templates using <code class="computeroutput"><span class="identifier">requires</span></code> within the <code class="computeroutput"><a class="link" href="../CONTRACT_CLASS.html" title="Macro CONTRACT_CLASS">CONTRACT_CLASS</a></code>
+        macro, after the template parameter declarations (see also the <a class="link" href="grammar.html" title="Grammar">Grammar</a>
+        section):

+</pre>
+<p>
+        The following example requires that the generic type <code class="computeroutput"><span class="identifier">T</span></code>
+        specified for the class template <code class="computeroutput"><span class="identifier">vector</span></code>
+        is always CopyConstructible
+        and it uses the <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">CopyConstructible</span></code> concept defined by Boost.ConceptCheck

+            The function bodies need to be specified within the macros and that will
+            make compiler errors very hard to use (because the errors will all refer
+            to the same line number, the line number on which the <code class="computeroutput"><span class="identifier">CONTRACT_CONCEPT</span></code>
+            macro expanded). However, concept definitions, including possible function
+            bodies, might be simple enough for this not to be a major issue at least
+            in the most common cases (the authors do not have enough experience with

+<p>
+        The authors <span class="emphasis"><em>think</em></span> this syntax can be implemented and
+        parsed using the preprocessor however the authors have not tried to implement
+        this yet. If this syntax can indeed be implemented, it should then be investigated
+        if the actual concept definitions can be programmed from the parsed concept
+        traits using C++ (this seems possible at least for C++11
+        based on some work done for the Generic
+        library).
+      </p>
+<p>
+        The authors recognize that implementing concept definitions would be a nice
+        addition to this library (again, concepts are parts of the program specifications,
+        they are contracts on the type system that are checked at compile-time, so
+        both concept checking and concept definition are within the scope of this
+        library). However, at the moment there are no concrete plans for extending
+        this library with the concept definitions (see also <a href="https://sourceforge.net/apps/trac/contractpp/ticket/49" target="_top">Ticket
+        49</a>).
+      </p>
+<p>
+        The following is a side-by-side comparison of this possible concept definition

+        It is a common Contract Programming requirement to disable other contracts
+        while a contract assertions is being evaluated (in order to avoid infinite
+        recursive calls). This library implement this feature however it should be
+        noted that in order to globally disable assertions while checking another
+        assertion, some type of global variable needs to be used. In multi-threaded
+        environments, programmers can define the <code class="computeroutput"><a class="link" href="../CONTRACT_CONFIG_THREAD_SAFE.html" title="Macro CONTRACT_CONFIG_THREAD_SAFE">CONTRACT_CONFIG_THREAD_SAFE</a></code>
+        configuration macro to protect such a global variable from racing conditions
+        (but that will effectively introduce a global lock in the program).

+        A limited form of Contract Programming is the use of the C++ <code class="computeroutput"><span class="identifier">assert</span></code> macro. Using <code class="computeroutput"><span class="identifier">assert</span></code>

+                  Using function preconditions and postconditions, programmers can

+                  at its entry and what it ensures under its (normal) exit. In particular,

+                  mechanism that allows programmers to compare values of an expression
+                  before and after the function body execution. This mechanism is
+                  powerful enough to enable programmers to express many constraints
+                  within the code, constraints that would otherwise have to be captured
+                  at best only informally by the code documentation.

+                  Using class invariants, programmers can describe what to expect

+                  Contract Programming can provide a powerful debugging facility

+                  than at some later stage of the program execution in an apparently
+                  unrelated manner. Note that a precondition failure points to a

+                  to a bug in the function implementation. Furthermore, in case of

+                    Of course, if the contract is ill written then Contract Programming

+                    body only. For example, consider the validation of a result in

+        during testing. On the other hand, checking function arguments using postconditions

+        Contracts are most useful when they assert conditions only using public members.
+        For example, the caller of a member function cannot in general make sure
+        that the member function preconditions are satisfied if these preconditions
+        use private members that are not accessible by the caller. Therefore, a failure
+        in the preconditions will not necessarily indicate a bug in the caller given
+        that the caller was not able to fully check the preconditions before calling
+        the member function. In most cases, the need of using non-public members
+        to check contracts indicates an error in the design of the class. However,
+        given that C++ provides programmers ways around access level restrictions
+        (e.g., <code class="computeroutput"><span class="keyword">friend</span></code> and function pointers),
+        this library leaves it up to the programmers to make sure that only public
+        members are used in contract assertions (<a class="link" href="bibliography.html#N1962_anchor">[N1962]</a>
+        follows the same approach not forcing contracts to only use public members,

+        Finally, only public member functions shall check class invariants. Private
+        and protected member functions are allowed to brake class invariants because

+        Typically, preprocessing tools external to the language work by transforming
+        specially formatted code comments into contract code that is then checked
+        at run-time. One of this library primary goals was to support Contract Programming
+        entirely within C++ and without using any tool external to the standard language
+        (C++ macros were used instead of external preprocessing tools).
+      </p>
+<p>
+        To the authors' knowledge, this the only library that fully support Contract
+        Programming for C++ (see the <a class="link" href="bibliography.html" title="Bibliography">Bibliography</a>
+        section for the complete list of Contract Programming references studied
+        by the authors).

+            This library macros always need to expand to generate the class and function
+            declarations even when contract compilation is disabled. That is why
+            there is a compile-time overhead, even if significantly smaller, also
+            when contracts are all disabled (in this case however there is zero run-time
+            overhead). The compilation time overhead when all contracts are turned
+            off could be further reduced by optimizing the library implementation
+            to not include internal headers that are not required when contracts
+            are off (this type of optimizations will be a major focus on future releases).
+          </p></div>
+<div class="footnote"><p><sup>[<a id="ftn.contract__.contract_programming_overview.costs.f1" href="#contract__.contract_programming_overview.costs.f1" class="para">7</a>] </sup>
+            There is essentially no gain in pre-compiling this library headers because
+            most of the compilation time is taken by expanding and compiling this
+            library macros as they appear in the user code (and not by the library
+            implementation code itself). Furthermore, pre-compiled headers should
+            be used with the usual care because they can complicate the build system
+            and they introduce extra dependencies that might limit the amount of
+            targets that can be built simultaneously in a parallel build. However,
+            if properly used, pre-compiled headers can significantly reduce re-compilation
+            time when using this library.
+          </p></div>

+          In C++, a free function is any function that is not a member function.

+              Static member functions cannot be virtual so they cannot be overridden
+              and they do not subcontract.
+            </p></div>
+<div class="footnote"><p><sup>[<a id="ftn.contract__.contract_programming_overview.destructor_calls.f0" href="#contract__.contract_programming_overview.destructor_calls.f0" class="para">10</a>] </sup>
+              For generality, this library does not require the destructor body to
+              not throw exceptions. However, in order to comply with the STL exception
+              safety requirements, destructors should never throw.
+            </p></div>
+<div class="footnote"><p><sup>[<a id="ftn.contract__.contract_programming_overview.destructor_calls.f1" href="#contract__.contract_programming_overview.destructor_calls.f1" class="para">11</a>] </sup>
+              In theory, destructors could have static postconditions (i.e., postconditions
+              that are not allowed to access the object which no longer exists after
+              destruction). Still destructors shall never have preconditions because
+              a destructor can be called at any point after the object is constructed
+              as long the class invariants hold. None of the Contract Programming
+              references that the authors have studied propose static postconditions
+              for destructor (neither <a class="link" href="bibliography.html#N1962_anchor">[N1962]</a>
+              nor <a class="link" href="bibliography.html#Meyer97_anchor">[Meyer97]</a>, but Eiffel
+              has no static data member). Future revisions of this library might
+              implement destructor static postconditions (e.g., a destructor postconditions
+              of a class that counts object instances could assert that the instance
+              counter stored in a static data member should be decreased of one because
+              the object has been destructed, see also <a href="https://sourceforge.net/apps/trac/contractpp/ticket/41" target="_top">Ticket
+              41</a>).

+<div class="footnote"><p><sup>[<a id="ftn.contract__.contract_programming_overview.constant_correctness.f0" href="#contract__.contract_programming_overview.constant_correctness.f0" class="para">12</a>] </sup>
+          As usual in C++, constant-correctness can be enforced at compile-time only
+          as long as programmers do not use <code class="computeroutput"><span class="keyword">const_cast</span></code>

+          In Contract Programming, it is usually important to selectively turn off
+          contract compilation to reduce run-time, binary size, and compilation-time
+          overhead associated with the contracts (see <a class="link" href="bibliography.html#Meyer97_anchor">[Meyer97]</a>).
+          This library guarantees zero run-time and binary size overhead when all
+          contracts are all turned off (however, even when contracts are all turned
+          off there is a limited compile-time overhead associated with expanding
+          the contract macros to generate the original class and function declarations).
+          Note that when contracts are turned off their assertions are completely
+          ignored by the compiler so the assertion code might not even be syntactically
+          correct.
+        </p></td></tr>
+</table></div>
+<p>
+        For example, the following commands compile and check preconditions and class
+        invariants, but they do not compile and check postconditions, block invariants,
+        and loop variants:
+      </p>
+<pre class="programlisting">$ g++ -DCONTRACT_CONFIG_NO_POSTCONDITONS -DCONTRACT_CONFIG_NO_BLOCK_INVARIANTS -DCONTRACT_CONFIG_NO_LOOP_VARIANTS ...   # For GCC.

+</pre>
+<p>
+        Other configuration macros are provided to customize other aspects of the
+        library. For example, the <code class="computeroutput"><a class="link" href="../CONTRACT_CONFIG_FUNCTION_ARITY_MAX.html" title="Macro CONTRACT_CONFIG_FUNCTION_ARITY_MAX">CONTRACT_CONFIG_FUNCTION_ARITY_MAX</a></code>
+        macro is used to specify the maximum number of function parameters and the

+          specified by programmers (e.g., the function name) with other symbols (e.g.,
+          special prefixes and line numbers) to make internal symbols with unique
+          names to avoid name clashes. These symbols are separated by the letter
+          <code class="computeroutput"><span class="identifier">X</span></code> when they are concatenated
+          so they read more easily during debugging (unfortunately, the underscore
+          character <code class="computeroutput"><span class="identifier">_</span></code> could not be
+          used instead of the letter <code class="computeroutput"><span class="identifier">X</span></code>
+          because if the original symbol already contained a leading or trailing
+          underscore, the concatenation could result in a symbol with double underscores
+          <code class="computeroutput"><span class="identifier">__</span></code> which is reserved by

+          of the library public interface and they are not documented however they
+          constitute a separate set of standalone libraries that could be added to
+          the library public interface in the future.

+        In general, an error in programming this library syntax will generate cryptic
+        compiler errors (often exposing internal code from this library and from
+        Boost.Preprocessor).
+        <sup>[<a name="contract__.grammar.f0" href="#ftn.contract__.grammar.f0" class="footnote">70</a>]</sup>
+      </p>
+<p>
+        There are intrinsic limitations on the amount of error checking that can
+        be implemented by this library because it uses the preprocessor to parse
+        its syntax (e.g., there is no way the preprocessor can gracefully detect
+        and report unbalanced round parenthesis <code class="computeroutput"><span class="special">(</span>
+        <span class="special">...</span> <span class="comment">/* missing closing
+        parenthesis here */</span></code> or an invalid concatenation symbol <code class="computeroutput"><span class="identifier">BOOST_PP_CAT</span><span class="special">(</span><span class="identifier">xyz</span><span class="special">,</span> <span class="special">::</span><span class="identifier">std</span><span class="special">::</span><span class="identifier">vector</span><span class="special">)</span></code>). In addition, for a given macro all compiler
+        error messages report the same line number (because macros always expand
+        on a single line) so line numbers are not very useful in identifying syntactic
+        errors.
+      </p>
+<p>
+        While the preprocessor imposes limits on the error checking that can be implemented,
+        the current version of this library does not focus on providing the best
+        possible syntax error messages (this will be the focus of future releases,
+        see also <a href="https://sourceforge.net/apps/trac/contractpp/ticket/44" target="_top">Ticket
+        44</a>).

+      The best way to resolve syntactic errors is for programmers to inspect the
+      code <span class="quote">&#8220;<span class="quote">by eye</span>&#8221;</span> instead of trying to make sense of the compiler
+      errors. This section is very useful for programmers to make sure that they
+      are using the syntax correctly.

+<p>
+        The syntax used by this library macros effectively defies a new language
+        within C++. More precisely, this library macros define a <a href="http://en.wikipedia.org/wiki/Domain-specific_language" target="_top">Domain-Specific
+        Embedded Language (DSEL)</a> that replaces the usual C++ syntax for class
+        and function declarations. This is the <span class="emphasis"><em>Language of Contract++</em></span>
+        (or <span class="emphasis"><em>LC++</em></span> for short).
+      </p>
+<p>
+        In contrast with other DSEL hosted by C++ which are parsed using template
+        meta-programming (e.g., Boost.Phoenix),
+        this library DSEL is parsed <span class="quote">&#8220;<span class="quote">one meta-programming level higher</span>&#8221;</span>
+        using preprocessor meta-programming. Using both processor meta-programming
+        and template meta-programming allows this library to implement rules like
+        this:
+      </p>
+<pre class="programlisting"><span class="emphasis"><em>if a member function is not public then it does not check the class invariants</em></span>
+</pre>
+<p>
+        This rule cannot be implemented using only template meta-programming because
+        it is not possible to check if a function is public using template meta-programming
+        introspection techniques. For example, it is not possible to implement a
+        boolean meta-function like the following: <sup>[<a name="contract__.grammar.preprocessor_dsel.f0" href="#ftn.contract__.grammar.preprocessor_dsel.f0" class="footnote">71</a>]</sup>

+</pre>
+<p>
+        Instead a macro can be programmed to parse the following function declarations

+        the function is public:

+        There are more examples of class and function declaration traits (<code class="computeroutput"><span class="keyword">virtual</span></code>, etc) that need to be known to correctly
+        implement Contract Programming but that cannot be inspected using template
+        meta-programming. This library macros can instead parse the specified class
+        and function declarations extracting <span class="emphasis"><em>any</em></span> declaration
+        trait (if a constructor is <code class="computeroutput"><span class="keyword">explicit</span></code>,

+        if a base class is <code class="computeroutput"><span class="keyword">protected</span></code>,

+        It should be noted that while the syntax of the DSEL defined by this library

+        Sometimes the C++ syntax allows to equivalently specify elements in different
+        orders (e.g., <code class="computeroutput"><span class="keyword">const</span> <span class="keyword">volatile</span></code>
+        and <code class="computeroutput"><span class="keyword">volatile</span> <span class="keyword">const</span></code>
+        are both allowed for member functions and they have the same meaning). The
+        syntax of this library requires instead to specify the elements exactly in
+        the order listed by this grammar (e.g., only <code class="computeroutput"><span class="keyword">const</span>
+        <span class="keyword">volatile</span></code> is allowed for member functions).

+        This is the syntax used to declare all functions: Free functions, member

+        of C++ function declarations apply: It is not possible to declare a static
+        virtual member function, only constructors can use the class name as the
+        function name, constructors and destructors have no result type, etc. The
+        <code class="computeroutput"><span class="keyword">static</span></code> specifier can only be
+        used for member functions (because it was deprecated for free functions from

+        appear after <code class="computeroutput"><span class="keyword">const</span></code> when they

+        For functions other than constructors and for constructors without member
+        initializers, function-try blocks are programmed outside the macros and around
+        the body definition as usual. As specified by <a class="link" href="bibliography.html#N1962_anchor">[N1962]</a>,
+        function-try blocks apply only to exceptions thrown by the function body
+        and not to exceptions thrown by the contracts themselves (if any) and by
+        the contract checking code generated by the library macros.
+      </p>
+<p>
+        Member initializers (and their function-try blocks) are part of the constructor
+        definition and not of the constructor declaration. However, C++03
+        lack of delegating constructors requires member initializers (and their function-try
+        blocks) to be specified within this library macros and constructors must
+        be defined together with their declarations when they use member initializers.

+        Some basic name manipulations are allowed at the local scope where the assertions
+        are being declared in case they are ever needed to simplify the assertion
+        expressions. Specifically, using-directives, namespace-aliases, and type-definitions
+        are allowed (these will always affect all assertions within the given preconditions,
+        postconditions, etc so it is recommended to always use these statement at
+        the very beginning before the actual assertion conditions). Note that these
+        name manipulations have no effect on the program run-time state and therefore
+        they do not compromise the contract constant-correctness requirement.

+<p>
+        As indicated by the grammar above, it is not possible to specify assertion

+        for the entire select assertion if-then-else expression. Eventual assertion
+        requirements must be specified for the single assertions within the select
+        assertion if-then-else statement and they will never disable compilation
+        and checking of the select assertion if-condition. Programmers can use the
+        ternary operator <code class="computeroutput"><span class="special">?:</span></code> instead
+        of a select assertion if they need to specify a guarded assertion with a
+        condition that is also disabled by the assertion requirements:

+        An advantage of this alternative syntax is that it does not require commas
+        at the end of each assertion. However, when compared with this library syntax,
+        the alternative syntax is overall more verbose, it uses more parenthesis,
+        it deviates more from <a class="link" href="bibliography.html#N1962_anchor">[N1962]</a> and Eiffel
+        (even if it is more similar to D),
+        and it looks less readable at least because of <code class="computeroutput"><span class="identifier">decl</span><span class="special">(...)</span></code> (in many ways this alternative syntax
+        is equivalent to the already supported sequencing syntax from the <a class="link" href="no_variadic_macros.html" title="No Variadic Macros">No
+        Variadic Macros</a> section with the addition of <span class="quote">&#8220;<span class="quote">decoration identifiers</span>&#8221;</span>
+        like <code class="computeroutput"><span class="identifier">assert</span></code> which might make
+        the code more readable but are not needed syntactically). Therefore, the
+        authors opted for implementing the syntax on the left hand side.

+          Usually, the complexity of C++ definitions is greater than the complexity

+          more complex by adding program specifications to them (preconditions, postconditions,
+          etc). Therefore, it can no longer be argued that declarations are significantly
+          simpler than definitions and it would be rather helpful to have sensible
+          compiler error messages at least for the declarations with contracts.

+          Even if that were possible in C++11,

+          in oder to properly implement Contract Programming (e.g., if a function

+      This section explains how to use this library to program named parameters and
+      deduced named parameters which are used instead of C++ usual positional parameters
+      to specify arguments to function calls. Parameter names are part of the program
+      specifications and therefore named parameters are within the scope of this
+      library.
+    </p>
+<p>
+      This library internally uses Boost.Parameter
+      to implement named parameters. This library only offers an easier syntax for
+      constructor and class template named parameters with respect the functionality
+      already provided by Boost.Parameter,
+      but this library allows to specify named parameters, concepts, and contracts
+      all together within a unified syntax.

+<p>
+        In C++, parameters are identified with respect to their declaration position
+        within the parameter list: The first call <span class="emphasis"><em>argument</em></span> (i.e.,
+        the specific value assigned to the formal parameter at the call site) maps
+        to the first declared parameter, the second call argument maps to the second
+        declared parameter, etc. For example:
+      </p>
+<pre class="programlisting"><span class="identifier">window</span><span class="special">*</span> <span class="identifier">make_window</span> <span class="special">(</span>
+        <span class="keyword">char</span> <span class="keyword">const</span><span class="special">&amp;</span> <span class="identifier">name</span><span class="special">,</span>
+        <span class="identifier">size_t</span> <span class="identifier">width</span> <span class="special">=</span> <span class="number">10</span><span class="special">,</span>
+        <span class="keyword">bool</span> <span class="identifier">moveable</span> <span class="special">=</span> <span class="keyword">true</span><span class="special">,</span>
+        <span class="keyword">bool</span> <span class="identifier">visible</span> <span class="special">=</span> <span class="keyword">true</span>
+    <span class="special">)</span>
+<span class="special">;</span>
+</pre>
+<p>
+        This protocol is sufficient when there is at most one parameter with a useful
+        default value but when there are even a few useful default parameters the
+        positional interface becomes difficult to use at the calling site. For example,
+        in the following call we need to repeat the default parameter value <code class="computeroutput"><span class="number">10</span></code>:
+      </p>
+<pre class="programlisting"><span class="keyword">bool</span> <span class="keyword">const</span> <span class="identifier">unmoveable</span> <span class="special">=</span> <span class="keyword">false</span><span class="special">;</span>
+<span class="identifier">make_window</span><span class="special">(</span><span class="string">"warning"</span><span class="special">,</span> <span class="number">10</span><span class="special">,</span> <span class="identifier">unmoveable</span><span class="special">);</span> <span class="comment">// Positional (usual).</span>
+</pre>
+<p>
+        Furthermore, it would be easier to understand the meaning of the arguments
+        at the calling site if the parameters could be referred by their names. For
+        example, in order to understand if the following window is moveable and invisible,
+        or unmoveable and visible, programmers at the calling site need to remember
+        the order of the parameter declarations:
+      </p>
+<pre class="programlisting"><span class="identifier">make_window</span><span class="special">(</span><span class="string">"note"</span><span class="special">,</span> <span class="number">10</span><span class="special">,</span> <span class="keyword">true</span><span class="special">,</span> <span class="keyword">false</span><span class="special">);</span> <span class="comment">// Positional (usual).</span>
+</pre>
+<p>
+        These issues would be solved if the parameter names could be referred at
+        the calling site and that is what <a href="http://en.wikipedia.org/wiki/Named_parameter" target="_top"><span class="emphasis"><em>named
+        parameters</em></span></a> allow to do:
+      </p>
+<pre class="programlisting"><span class="identifier">make_window</span><span class="special">(</span><span class="string">"warning"</span><span class="special">,</span> <span class="identifier">moveable</span> <span class="special">=</span> <span class="keyword">false</span><span class="special">);</span> <span class="comment">// Named.</span>
+<span class="identifier">make_widnow</span><span class="special">(</span><span class="string">"note"</span><span class="special">,</span> <span class="identifier">visible</span> <span class="special">=</span> <span class="keyword">false</span><span class="special">);</span>
+</pre>
+<p>
+        Named parameters were proposed for addition to early versions of C++ but
+        the proposal was never accepted (see <span class="quote">&#8220;<span class="quote">keyword arguments</span>&#8221;</span> in
+        <a class="link" href="bibliography.html#Stroustrup94_anchor">[Stroustrup94]</a>). Other programming
+        languages support named parameters (Ada,
+        Python, etc).
+      </p>
+<p>
+        Furthermore, <span class="emphasis"><em>deduced named parameters</em></span> are named parameters
+        that can be passed in any position and without supplying their names. These
+        are useful when functions have parameters that can be uniquely identified
+        (or <span class="emphasis"><em>deduced</em></span>) based on the argument types of the function
+        call. For example, the <code class="computeroutput"><span class="identifier">name</span></code>
+        parameter is such a parameter, it can be deduced because no other argument,
+        if valid, can be reasonably converted into a <code class="computeroutput"><span class="keyword">char</span>
+        <span class="keyword">const</span><span class="special">*</span></code>.
+        Therefore, with a deduced parameter interface, we could pass the window name
+        in any position without causing any ambiguity (with an appropriately designed
+        deduced parameter interface, the caller might not even have to remember the
+        actual parameter names):
+      </p>
+<pre class="programlisting"><span class="identifier">make_window</span><span class="special">(</span><span class="identifier">moveable</span> <span class="special">=</span> <span class="keyword">false</span><span class="special">,</span> <span class="string">"warning"</span><span class="special">);</span> <span class="comment">// Deduced.</span>

+        In the rare case that programmers need to use this library on compliers without

+        using a Boost.Preprocessor
+        sequence in which tokens are separated using round parenthesis <code class="computeroutput"><span class="special">()</span></code>:
+      </p>

+</pre>
+<p>
+        This library detects preprocessor support for variadic macros using the

+        Boost.Config

+        only on compilers that do not support variadic macros furthermore programmers
+        can forcefully define this macro also on compilers that support variadic
+        macros. When this macro is not defined, this library macros support both
+        the camma-separated and sequence syntax, otherwise only the sequence syntax

+        This is because if assertion conditions are programmed together using <code class="computeroutput"><span class="keyword">and</span></code> then it will not be clear which assertion

+          Contracts are most useful when the assertions only use public members that

+          might be the only compiler that supports them), they were removed from
+          C++11, and
+          they are an untested feature of this library. Instead of using <code class="computeroutput"><span class="keyword">export</span></code> templates, it is common practise
+          in C++ to program both template declarations and definitions together so
+          they can be compiled correctly. In this example, the authors have used
+          a separate header file <code class="computeroutput"><span class="special">...</span><span class="identifier">_impl</span><span class="special">.</span><span class="identifier">hpp</span></code> to logically separate template declarations
+          and definitions but the header is included at the bottom of the declaration
+          header file so the definitions are always available together with their
+          declarations.

+          are needed because contracts are disabled differently for the different

+          compliant (and, for example, it was fixed in more recent versions of GCC)
+          therefore programmers are advised to specify the template parameter names
+          only for the class type and not for the constructor and destructor names
+          (this is also why the macros must take a second parameter with the class
+          name instead of just the class type parameter).

+            <span class="bold"><strong>Rationale.</strong></span> This limitation comes from
+            the fact that C++03
+            does not support delegating constructors. If member initializers are
+            specified within the contract, the deferred body will not compile when
+            contract compilation is turned off by the configuration macros. If instead

+            the deferred body will not compile when contract compilation is turned
+            on by the configuration macros. There is no way to reconcile these two
+            conditions without delegating constructors, so definitions cannot be
+            deferred for constructors that specify member initializers. This limitation
+            could be removed in future revisions of this library for C++11

+      Contract Programming
+      (CP) allows to specify preconditions, postconditions, and class invariants
+      that are automatically checked when functions are executed at run-time. These
+      conditions assert program specifications within the source code itself allowing
+      to find bugs more quickly during testing, making the code self-documenting,
+      and increasing overall software quality.
+    </p>
+<p>
+      Contract Programming is also known as Design by Contract (DbC) <sup>[<a name="contract__.introduction.f0" href="#ftn.contract__.introduction.f0" class="footnote">1</a>]</sup> and it was first introduced by the Eiffel
+      programming language (see <a class="link" href="contract__/bibliography.html#Meyer97_anchor">[Meyer97]</a>).
+      All Contract Programming features of the Eiffel
+      programming language are supported by this library, among others (see also
+      the <a class="link" href="contract__/contract_programming_overview.html#contract__.contract_programming_overview.features" title="Features">Features</a>
+      section):

+<p>
+      In addition, this library supports virtual specifiers, concept checking, and
+      named parameters which together with contracts specify requirements of the
+      program interface. This library is implemented for the C++03
+      standard and it does not require C++11.

+      is equal to <code class="computeroutput"><span class="identifier">max_size</span></code> then the

+      caller:
+    </p>
+<pre class="programlisting">precondition number 1 "size() &lt; max_size()" failed: file "push_back.cpp", line 26

+<p>
+      Instead, if there is a bug in the <code class="computeroutput"><span class="identifier">push_back</span></code>
+      implementation for which <code class="computeroutput"><span class="identifier">size</span></code>
+      is not increased by one after <code class="computeroutput"><span class="identifier">value</span></code>
+      is added to <code class="computeroutput"><span class="identifier">vector</span></code> by the function
+      body then the execution will be interrupted reporting a failure of the first

+<pre class="programlisting">postcondition number 1 "size() == old_size + 1" failed: file "push_back.cpp", line 26

+      By default, when assertions fail this library prints the above error messages

+      <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">terminate</span></code> (this behaviour can be customized
+      to throw an exception, exit the program, etc, see the <a class="link" href="contract__/contract_programming_overview.html#contract__.contract_programming_overview.broken_contracts" title="Broken Contracts">Broken
+      Contracts</a> section). Note that the library error messages contain enough
+      information to uniquely identify the contract failure: Assertion type (class
+      invariant, precondition, postcondition, etc), assertion number, asserted expression,
+      file name, and line number. (The line number refers to the single line on which
+      each macro expands so it will be the same for class invariants, preconditions,
+      and postconditions of a given class or function but it can still be used together
+      with the assertion number to uniquely identity which assertion failed.)

+      and the lack of consideration for the Contract Programming proposal <a class="link" href="contract__/bibliography.html#N1962_anchor">[N1962]</a>,

+[section Introduction]
+
+[@http://en.wikipedia.org/wiki/Design_by_contract Contract Programming] (CP) allows to specify preconditions, postconditions, and class invariants that are automatically checked when functions are executed at run-time.
+These conditions assert program specifications within the source code itself allowing to find bugs more quickly during testing, making the code self-documenting, and increasing overall software quality.
+
+Contract Programming is also known as Design by Contract (DbC)
+[footnote
+Design by Contract is a registered trademark of [@http://en.wikipedia.org/wiki/Eiffel_Software Eiffel Software].
+]
+and it was first introduced by the __Eiffel__ programming language (see __Meyer97__).
+All Contract Programming features of the __Eiffel__ programming language are supported by this library, among others (see also the __Features__ section):
+
+# Support for preconditions, postconditions, class invariants, block invariants, and loop variants.
+# Subcontract derived classes (with support for pure virtual functions and multiple inheritance).
+# Access expression old values and function return value in postconditions.
+# Optional compilation and checking of preconditions, postconditions, class invariants, block invariants, and loop variants.
+# Customizable actions on contract assertion failure (terminate by default but it can throw, exit, etc).
+
+In addition, this library supports virtual specifiers, concept checking, and named parameters which together with contracts specify requirements of the program interface.
+This library is implemented for the __CXX03__ standard and it does not require __CXX11__.
+
+[heading An Example]
+
+The example below shows how to use this library to program contracts for the C++ Standard Template Library (STL) member function [@http://www.sgi.com/tech/stl/BackInsertionSequence.html `std::vector::push_back`] (in order to illustrate subcontracting, the `vector` class inherits from the somewhat arbitrary `pushable` base class).
+The syntax used by this library is compared side-by-side with the syntax proposed by __N1962__ for adding Contract Programming to C++ (see also [@../../example/contracts/push_back.cpp =push_back.cpp=] and [@../../example/contracts/pushable.hpp =pushable.hpp=]):
+
+[import ../example/contracts/push_back.cpp]
+[import ../example/contracts/push_back_lines.cpp]
+[import ../example/contracts/push_back_npaper.cpp]
+[table
+    [ [#] [This Library (C++03)] [N1962 and N2081 Proposals (not adopted by C++11)
+[footnote
+Unfortunately, the Contract Programming proposal __N1962__ and the concept proposal __N2081__ were never adopted by the C++ standard so the example on the right hand side will not compile.
+]   
+    ] ]
+    [ [[push_back_lines]] [[push_back]] [[push_back_npaper]] ]
+]
+
+Classes and functions are declared using the [macroref CONTRACT_CLASS] and [macroref CONTRACT_FUNCTION] macros respectively.
+Class invariants must appear at the very beginning of the class definition and they are specified using the [macroref CONTRACT_CLASS_INVARIANT] macro.
+The `TPL` postfixes indicate versions of the macros that need to be used within templates.
+
+Note the following differences between the syntax used by this library macros and the usual C++ declaration syntax (see the __Differences_with_CXX_Syntax__ section for a complete list):
+
+* Round parenthesis `template( ... )` are used instead of angular parenthesis `template< ... >` to declare templates (line 7).
+* Similarly to __N2081__, the specifier `requires( ... )` is used to specify concepts to check (line 7).
+* The class and function names are wrapped within round parenthesis `(vector)` and `(push_back)` (lines 8 and 18).
+* The specifier `extends( ... )` is used instead of the column symbol `:` to inherit from base classes (line 8).
+This automatically subcontracts `vector` from `pushable` (when subcontracting, derived and base preconditions are checked in __logic_or__, derived and base postconditions are checked in __logic_and__, derived and base class invariants are checked __logic_and__).
+* The access level `public`, `protected`, or `private` must always be specified for member functions but without the trailing column symbol `:` (line 18).
+* The function result and parameter types are wrapped within round parenthesis `(T const&)` (line 18).
+The parenthesis are allowed but not required for fundamental types that contain no symbol (e.g., the function result type `void` at line 18, but also `bool`, `unsigned int const`, etc).
+* Similarly to __CXX11__, the specifier `override` is used to check that a member function is indeed overriding a base member function (line 18).
+* The specifiers `precondition( ... )` and `postcondition( ... )` are used to program function preconditions and postconditions (lines 19 and 22).
+Furthermore, the [macroref CONTRACT_OLDOF] macro can be used within postconditions to declare variables and initialize them to old values that the specified expressions had before executing the function body (line 23).
+* Class invariants, preconditions, and postconditions assert boolean expressions separated by commas `,` (lines 11, 20, and 24).
+
+Finally, note that the class and function definitions are programmed outside the macros so they retain their usual C++ syntax (e.g., the function body at line 27).
+
+The library executes the following steps when the `push_back` function is called at run-time (see also the __Contract_Programming_Overview__ section):
+
+# First, the class invariants and the function preconditions are checked.
+# Then, the function body is executed.
+# Last, the class invariants and the function postconditions are checked.
+
+For example, if there is a bug in the function caller for which `push_back` is called when `size` is equal to `max_size` then the execution of the program will be interrupted reporting a failure of the first assertion in the preconditions and it will be evident that the bug is in the caller:
+
+[pre
+    precondition number 1 "size() < max_size()" failed: file "push_back.cpp", line 26
+]
+
+Instead, if there is a bug in the `push_back` implementation for which `size` is not increased by one after `value` is added to `vector` by the function body then the execution will be interrupted reporting a failure of the first assertion in the postconditions and it will be evident that the bug is in `push_back` body:
+
+[pre
+    postcondition number 1 "size() == old_size + 1" failed: file "push_back.cpp", line 26
+]
+
+By default, when assertions fail this library prints the above error messages to the standard error `std::cerr` and it terminates the program calling `std::terminate` (this behaviour can be customized to throw an exception, exit the program, etc, see the __Broken_Contracts__ section).
+Note that the library error messages contain enough information to uniquely identify the contract failure: Assertion type (class invariant, precondition, postcondition, etc), assertion number, asserted expression, file name, and line number.
+(The line number refers to the single line on which each macro expands so it will be the same for class invariants, preconditions, and postconditions of a given class or function but it can still be used together with the assertion number to uniquely identity which assertion failed.)
+
+[heading Language Support]
+
+This library suffers of two limitations:
+
+# The unusual syntax used to declare classes and functions within the macros which causes cryptic compiler errors when not used correctly (syntax error checking and reporting could be somewhat improved in future revisions of the library but there are fundamental limitations on what can be done using the preprocessor, see also the [link syntax_error_warning_anchor Grammar] section).
+# High compilation times (the authors will try to reduce compilation times in future revisions of the library, see also the [link compilation_time_warning_anchor Cost]  section).
+
+With the addition of contracts, concepts, and named parameters, C++ could introduce formal program specification into main-stream programming.
+The authors wish the work done in developing this library will persuade the C++ community and the C++ standard committee to add these features to the core language so to support formal program specification without the unusual macro syntax and avoiding high compilation times (unfortunately, this has not been the direction taken for __CXX11__ with the rejection of the concept proposal __N2081__ and the lack of consideration for the Contract Programming proposal __N1962__, but there might still be hope for C++1x with x > 1).

+[section Named Parameters]
+
+This section explains how to use this library to program named parameters and deduced named parameters which are used instead of C++ usual positional parameters to specify arguments to function calls.
+Parameter names are part of the program specifications and therefore named parameters are within the scope of this library.
+
+This library internally uses __Boost_Parameter__ to implement named parameters.
+This library only offers an easier syntax for constructor and class template named parameters with respect the functionality already provided by __Boost_Parameter__, but this library allows to specify named parameters, concepts, and contracts all together within a unified syntax.
+
+[section Overview]
+
+In C++, parameters are identified with respect to their declaration position within the parameter list: The first call /argument/ (i.e., the specific value assigned to the formal parameter at the call site) maps to the first declared parameter, the second call argument maps to the second declared parameter, etc.
+For example:
+    
+    window* make_window (
+            char const& name,
+            size_t width = 10,
+            bool moveable = true,
+            bool visible = true
+        )
+    ;
+
+This protocol is sufficient when there is at most one parameter with a useful default value but when there are even a few useful default parameters the positional interface becomes difficult to use at the calling site.
+For example, in the following call we need to repeat the default parameter value `10`:
+    
+    bool const unmoveable = false;
+    make_window("warning", 10, unmoveable); // Positional (usual).
+
+Furthermore, it would be easier to understand the meaning of the arguments at the calling site if the parameters could be referred by their names.
+For example, in order to understand if the following window is moveable and invisible, or unmoveable and visible, programmers at the calling site need to remember the order of the parameter declarations:
+
+    make_window("note", 10, true, false); // Positional (usual).
+
+These issues would be solved if the parameter names could be referred at the calling site and that is what [@http://en.wikipedia.org/wiki/Named_parameter ['named parameters]] allow to do:
+
+    make_window("warning", moveable = false); // Named.
+    make_widnow("note", visible = false);
+
+Named parameters were proposed for addition to early versions of C++ but the proposal was never accepted (see ["keyword arguments] in __Stroustrup94__).
+Other programming languages support named parameters (__Ada__, __Python__, etc).
+
+Furthermore, /deduced named parameters/ are named parameters that can be passed in any position and without supplying their names.
+These are useful when functions have parameters that can be uniquely identified (or /deduced/) based on the argument types of the function call.
+For example, the `name` parameter is such a parameter, it can be deduced because no other argument, if valid, can be reasonably converted into a `char const*`.
+Therefore, with a deduced parameter interface, we could pass the window name in any position without causing any ambiguity (with an appropriately designed deduced parameter interface, the caller might not even have to remember the actual parameter names):
+
+    make_window(moveable = false, "warning"); // Deduced.
+    make_window("note", visible = false);
+
+The same reasoning applies to named template parameters and deduced named template parameters:
+
+    template< typename ValueType, bool Shared = true >
+    class smart_ptr ;
+
+    smart_ptr<std::string, false> p1;                       // Positional (usual).
+    smart_ptr<false, std::string> p2;                       // Deduced.
+    smart_ptr<Shared = false, ValueType = std::string> p3;  // Named.
+
+[endsect]
+
+[section Named Function Parameters]
+
+To show how to program named parameters, we will program a named parameter interface for the [@http://www.boost.org/doc/libs/1_49_0/libs/graph/doc/depth_first_search.html Depth First Search (DFS)] algorithm of the __Boost_Graph__ library:
+
+    template<
+        class Graph,
+        class Visitor,
+        class IndexMap,
+        class ColorMap
+    > requires
+        is_incidence_and_vertex_list_graph<Graph>,
+        is_integral_property_map_of_key<IndexMap, vertext_descriptor<Graph> >,
+        is_property_map_of_key<ColorMap, vertex_descriptor<Graph> >
+    void depth_first_search (
+            Graph const& graph,
+            Visitor const& visitor = dfs_visitor<>(),
+            vertex_descriptor<Graph> const& root_vertex =
+                    *vertices(graph).first,
+            IndexMap const& index_map = get(vertex_index, graph),
+            ColorMap& color_map =
+                    default_color_map(num_vertices(graph), index_map)
+        )
+    ;
+
+This is non-valid C++ code but it can be considered pseudo-code to illustrate the function interface that we need to program.
+The concept syntax `requires` was ["borrowed] here to express parameter type requirements but a failure to satisfy such requirements is intended to fail the function call resolution and not to cause a concept error as usual.
+
+[variablelist
+[ [=graph=] [
+This is an input parameter (`const&`), its type must match a model of both `IndicenceGraph` and `VertexListGraph`, and it has no default value (required parameter).
+] ]
+[ [=visitor=] [
+This is an input parameter (`const&`), its type has no requirement, and its value defaults to a DFS visitor (optional parameter).
+] ]
+[ [=root_vertex=] [
+This is an input parameter (`const&`), its type must be `vertex_descriptor<Graph>`, and its value defaults to the first vertex of the specified graph (optional parameter).
+] ]
+[ [=index_map=] [
+This is an input parameter (`const&`), its type must match a model of `IntegralPropertyMap` with key type `vertex_descriptor<Graph>`, its value defaults to the vertex index of the specified graph (optional parameter).
+] ]
+[ [=color_map=] [
+This is an input and output parameter (non-constant reference `&`), its type must match a model of `PropertyMap` with key type `vertex_descriptor<Graph>`, its value defaults to a map with size equal to the number of vertices of the specified graph and created from the specified `index_map` (optional parameter).
+] ]
+]
+
+[*Parameter Identifiers]
+
+First of all, it is necessary to declare special elements that will serve as the parameter and argument identifiers (see also [file example/named_parameters named_params_dfs.cpp]):
+
+[import ../example/named_parameters/named_params_dfs.cpp]
+[named_params_dfs_keywords]
+
+For example, the first [macroref CONTRACT_PARAMETER] macro declares an identifier `graph` that is used as the parameter name in the function declaration and also an identifier `graph_` (note the trailing underscore `_`) that is used to name the argument at the call site.
+
+[note
+By default, argument identifiers are differentiated from parameter identifiers using a trailing underscore `_` to avoid name clashes (see also the __Parameter_Identifiers__ section).
+Furthermore, it is recommended to always declare these identifiers within a namespace to avoid name clashes (because different functions in different sections of the code might very well use the same parameter names so namespaces can be used to control overlapping names).
+]
+
+For example, for a library named Graphs, all named parameter identifiers could be declared under the `graphs` namespace and maybe in a single header =graphs_params.hpp=.
+Many different functions within `graphs` (for example `graphs::depth_first_search` and `graphs::breadth_first_search`) will share a number of common parameter names (for example a parameter named `graph` with parameter identifier `graphs::graph` and argument identifier `graphs::graph_`).
+All these named parameters will be defined in one places in =graphs_params.hpp= and within the `graphs` namespace so programmers can conveniently control and avoid named clashes.
+
+[*Function Declaration]
+
+The function is declared using the following syntax (see also [file example/named_parameters named_params_dfs.cpp]):
+
+[named_params_dfs_decl]
+
+This example required no preconditions and no postconditions.
+
+[*In, In Out, and Out Parameters]
+
+Input parameters (i.e., constant references `const&`) are prefixed by the specifier `in` (see also the __Grammar__ section):
+
+    in ... graph // Input parameter.
+
+Input and output parameters (i.e., non-constant reference `&`) are prefixed by both specifiers `in out` (in this order, see also the __Grammar__ section):
+
+    in out ... color_map // Input-output parameter.
+
+Output parameters can be prefixed just by the specifier `out` but their implementation is equivalent to using the specifiers `in out` (i.e., non-constant reference `&`).
+[footnote
+*Rationale.*
+C++ cannot express the semantics that an output parameter should be written and never read within a function because references can always be both written and read.
+]
+Note that a named parameter must always be specified either `in`, `in out`, or `out` (and that is what distinguish syntactically a named parameter from a positional parameter; this use of `in`, `in out`, and `out` resembles __Ada__'s syntax).
+Named and positional parameters cannot be used together in the same function declaration.
+
+[*Parameter Types]
+
+Exact parameter types are specified just before the parameter name and within parenthesis (unless they are fundamental types containing no symbol, see also the __Grammar__ section):
+
+    in (vertex_descriptor<CONTRACT_PARAMETER_TYPEOF(graph)>) root_vertex // Exact parameter type requirement.
+
+Generic parameter types (i.e., parameter types with no requirement, same as usual type template parameters) are specified using `auto` instead of the parameter type (see also the __Grammar__ section):
+
+    in auto visitor // No parameter type requirement.
+
+Predicate parameter type requirements are specified using `requires(`[^['unary-boolean-metafunction]]`)` instead of the parameter type, the type of the argument specified by the function call will be required to match the specified unary boolean meta-function in order for the call to be resolved (see also the __Grammar__ section):
+
+    in requires(is_incidence_and_vertex_list_graph<boost::mpl::_>) graph // Predicate parameter type requirement.
+
+The placeholder `boost::mpl::_` makes this expression a unary meta-function (see __Boost_MPL__) and the library will substitute such a placeholder with the argument type specified at the call site when resolving the function call.
+
+[*Default Parameter Values]
+
+Default parameter values are specified using `, default `[^['default-parameter-value]] right after the parameter declaration (see also the __Grammar__ section):
+
+    in auto visitor, default boost::dfs_visitor<>()
+
+Default parameter values are not evaluated and their types are not even instantiated if an actual argument is specified by the function call.
+
+[note
+The type and value of a parameters can be used within the declaration of other parameters.
+The type of a named parameter can be accessed using the [macroref CONTRACT_PARAMETER_TYPEOF] macro (this is especially useful for generic parameter types and for parameter types with predicate requirements because these types are not known until the function call is resolved).
+]
+
+[*Function Call]
+
+The `graphs::depth_first_search` function can be called using argument identifiers to name its parameters (see also [file example/named_parameters named_params_dfs.cpp]):
+
+[named_params_dfs_call]
+
+[endsect]
+
+[section Deduced Function Parameters]
+
+To show how to program deduced named parameters, we program the parameter interface for the [@http://www.boost.org/doc/libs/1_49_0/libs/python/doc/v2/def.html#def-spec `def`] function of the __Boost_Python__ library (see also [file example/named_parameters deduced_params_pydef.cpp]):
+
+[import ../example/named_parameters/deduced_params_pydef.cpp]
+[deduced_params_pydef_decl]
+
+Also a precondition was specified in this example.
+(Concepts for named parameters are explained later in this section.)
+
+Deduced parameters are named parameter that are prefixed by the `deduce` specifier (see also the __Grammar__ section):
+
+    deduce in (char const*) docstring // Deduced input parameter.
+
+When calling the function `py::def` only two arguments are required `name` and `func`.
+The association between any addition argument and its parameter can be deduced based on the types of the arguments specified by the function call (so the caller is neither required to remember the parameter positions nor to explicitly specify the parameter names for these arguments).
+
+For example, the first two calls below are equivalent and if programmers need to pass a `policy` argument that is also, for some reason, convertible to `char const*`, they can always specify the parameter name as in the third call below (see also [file example/named_parameters deduced_params_pydef.cpp]):
+
+[deduced_params_pydef_calls]
+
+[endsect]
+
+[section Member Function Parameters]
+
+The same syntax is used to specify named and deduced parameters for member functions (see also [file example/named_parameters member_named_params_callable2.cpp]):
+
+[import ../example/named_parameters/member_named_params_callable2.cpp]
+[member_named_params_callable2]
+
+No contracts were specified in this example.
+
+[note
+When the body definition of a function with named parameters is deferred from the function declaration, the body must be declared as a template function when it is defined and the special macro [macroref CONTRACT_PARAMETER_BODY] must be used to name the function.
+]
+
+The same macro is used to name both free and member body functions because the class type is specified outside this macro.
+The constructor body definition cannot be deferred from the constructor declaration (because of the lack of delegating constructors in __CXX03__).
+Destructors have no named parameters (because they have no parameter).
+Named parameters are not supported for operators (because of a __Boost_Parameter__ bug).
+[footnote
+*Rationale.*
+This library syntax supports named and deduced parameters for operators.
+However, __Boost_Parameter__ does not compile when used with operators because of a bug (__Boost_Parameter__ documentation claims support for operators but later revisions of __Boost_Parameter__ no longer compile when operators are used).
+If __Boost_Parameter__ were to be fixed to work with operators then this library named and deduced parameters should also work with operators.
+]
+Therefore the [macroref CONTRACT_PARAMETER_BODY] macro is used only with free and member functions that are not operators.
+[footnote
+*Rationale.*
+A macro [macroref CONTRACT_PARAMETER_BODY] different from [macroref CONTRACT_MEMBER_BODY] and [macroref CONTRACT_FREE_BODY] is necessary because named parameters will still be enabled even when contracts are turned off using [macroref CONTRACT_CONFIG_NO_PRECONDITIONS], etc.
+]
+
+In this example, named parameters were specified for all `callable2::call` overloads and for the `static` member function `callable2:static_call`:
+
+[member_named_params_callable2_calls]
+
+[endsect]
+
+[section Constructor Parameters]
+
+The same syntax is used to specify named and deduced parameters for constructors (see also [file example/named_parameters constructor_named_params_family.cpp]):
+[footnote
+Arguably, this library offers a better syntax than __Boost_Parameter__ for constructor named and deduced parameters (because __Boost_Parameter__ requires boiler-plate code and an extra base class in order to handle constructors).
+]
+
+[import ../example/named_parameters/constructor_named_params_family.cpp]
+[constructor_named_params_family]
+
+Both preconditions and postconditions were specified for the constructor.
+
+[important
+Member initializers must access named and deduced parameters using the special macro [macroref CONTRACT_CONSTRUCTOR_ARG] (otherwise the compiler will generate an error).
+[footnote
+*Rationale.*
+This limitation comes from the lacks of delegating constructors in __CXX03__ (as with all other limitations of this library related to member initializers).
+]
+]
+
+Named and deduced parameters can be used to specify the arguments when constructing the object:
+
+[constructor_named_params_family_call]
+
+[endsect]
+
+[section Class Template Parameters]
+
+Only class templates are discussed in this section because function templates are effectively always declared when a function uses named or deduced parameters.
+In fact, a function with named or deduced parameters is always a function template (possibly with fully generic templated types when the named and deduced parameters types are specified `auto`).
+
+To show how to program named and deduced template parameters, we will program a named parameter interface for the [@http://www.boost.org/doc/libs/1_49_0/libs/python/doc/v2/class.html#class_-spec `class_`] class template of the __Boost_Python__ library:
+
+    template<
+        class ClassType,
+        class Bases = bases<>,
+        typename HeldType = not_sepcified,
+        typename Copyable = not_specified
+    > requires
+        is_class<ClassType>
+    class class_ ;
+
+[variablelist
+[ [ClassType] [
+This type parameter must be a class and it has no default value (required parameter).
+] ]
+[ [Bases] [
+This type parameter must be a specialization of `boost::python::bases` specifying base classes if any (see `boost::python::detail::specifies_bases`) and its value defaults to `boost::python::bases<>`.
+] ]
+[ [HeldType] [
+This type parameter has no constraint and it is not specified by default (see `boost::python::detail::not_specified`).
+] ]
+[ [Copyable] [
+This type parameter must be `boost::noncopyable` if specified and it is not specified by default (see `boost::python::detail::not_specified`).
+] ]
+]
+
+[important
+Unfortunately, named and deduced template parameters can only handle type template parameters (i.e., value template parameters and template template parameters are not supported).
+[footnote
+*Rationale.*
+This library only supports named and deduced type template parameter because it internally uses __Boost_Parameter__ and __Boost_Parameter__ does not support non-type template parameters.
+However, this library syntax would support named and deduced value template parameters and template template parameters if these were ever supported by __Boost_Parameter__ (see template parameters within the __Grammar__ section).
+Named and deduced value template parameters can be emulated by wrapping their values into types (using `boost::mpl::int_`, `boos::mpl::bool_`, etc) at the cost of a somewhat cumbersome syntax.
+]
+]
+
+First of all, it is necessary to declare elements that will serve as template parameter and argument identifiers (see also [file example/named_parameters named_template_params_pyclass.cpp]):
+
+[import ../example/named_parameters/named_template_params_pyclass.cpp]
+[named_template_params_pyclass_keywords]
+
+For example, the first [macroref CONTRACT_TEMPLATE_PARAMETER] macro declares a specifier `ClassType` that can be used as the parameter name in the class template declaration and a specifier `ClassType_` (note the trailing underscore `_`) that can be used for the template argument at the template instantiation site.
+
+[note
+By default, template argument identifiers are differentiated from template parameter identifiers using a trailing underscore `_` to avoid name clashes (see also the __Parameter_Identifiers__ section).
+Furthermore, it is recommended to always declare these identifiers within a namespace to avoid name clashes (because different class templates in different sections of the code might very well use the same template parameter names so namespaces can be used to control overlapping names).
+]
+
+The class template is declared using a syntax similar to the one we have seen so far for named and deduced function parameters (see also [file example/named_parameters named_template_params_pyclass.cpp]):
+[footnote
+Arguably, this library offers a better syntax than __Boost_Parameter__ for named and deduced template parameters (because __Boost_Parameter__ requires boiler-plate code and the additional argument packing types to be programmed manually).
+]
+
+[named_template_params_pyclass]
+
+Note that template parameters are always specified using `in` because they are always input parameters (they are static types).
+Furthermore, `typename` or `class` must always follow the `in` specifier for type template parameters.
+[footnote
+*Rationale.*
+This syntax was designed so it can support non-type template parameters if this library and __Boost_Parameter__ were ever extended to support value template parameters and template template parameters (see template parameters in the __Grammar__ section).
+]
+Predicate type requirements `requires(`[^['unary-boolean-metafunction]]`)` are optional and they are specified right after `typename` or `class` if present.
+Default template parameter values are specified using `, default `[^['default-parameter-value]] as usual.
+(See also the __Grammar__ section.)
+
+The class template `py::class_` can be instantiated using the template parameter identifiers to name the arguments (see also [file example/named_parameters named_template_params_pyclass.cpp]):
+[footnote
+This named and deduced parameter syntax is not entirely ideal because it uses angular parenthesis `py::ClassType_<bx>` instead of the more readable assignment operator `py::ClassType_ = bx` to name the arguments (but that is how __Boost_Parameter__ is implemented and also this library authors see no way to implement the assignment operator syntax for named and deduced template parameters).
+]
+
+[named_template_params_pyclass_calls]
+
+[endsect]
+
+[section Concepts]
+
+As shown in the `py::class_` example above, it is possible to specify concepts for named and deduced template parameters.
+Concepts are specified using `requires` after the class template parameter declaration:
+
+    template( ... ) requires( ``[^['concept1]]``, ``[^['concept2]]``, ... )
+    class (class_) ...
+
+As shown in the `py::def` example earlier in this section, it is also possible to specify concepts for named and deduced function parameters (because named and deduced function parameter can be generic, as function template parameters are, when their types are specified `auto` or via a predicate type requirement).
+However, in this case concepts are specified using `requires` after the function parameter list (because there is not `template` declaration for functions with named and deduced parameters):
+
+    void (def) ( ... ) requires( ``[^['concept1]]``, ``[^['concept2]]``, ... )
+
+Note the following differences between specifying predicate type requirements and concepts for named and deduced parameters:
+
+* If predicate type requirements are not met, the function or class template will be taken out from the set of possible function overloads or template specializations in the function call or template instantiation resolution (this might ultimately generate a compiler error but only if there is no other function overload or template specialization that can be used).
+* If a concept check fails, the compiler will always generate a compiler error.
+
+[endsect]
+
+[section Parameter Identifiers]
+
+When using the [macroref CONTRACT_PARAMETER] and [macroref CONTRACT_TEMPLATE_PARAMETER] macros (see also the __Grammar__ section):
+
+# It is possible to specify a namespace that will contain the parameter identifiers using `namespace(`[^['parameter-identifier-namespace]]`)`.
+# It is also possible to specify the name of the argument identifier instead of using the automatic underscore `_` postfix using `(`[^['argument-identifier]]`)`.
+
+The following example generates parameter identifiers within the `params` namespace, and argument identifiers `NumberArg` and `value_arg` instead of the default `Number_` and `value_` for the `Number` and `value` parameters respectively (see also [file example/named_parameters named_param_identifiers_positive.cpp]):
+
+[import ../example/named_parameters/named_param_identifiers_positive.cpp]
+[named_param_identifiers_positive_keywords]
+
+When the parameter identifier namespace is specified, it must be repeated in the named and deduced parameter declaration list (see also the __Grammar__ section):
+
+    using namespace ``/paraemeter-identifier-namespace/``, ... // named and deduced parameters follow
+
+The authors find this syntax confusing so they recommend to never specify the parameter identifier namespace when using the [macroref CONTRACT_PARAMETER] and [macroref CONTRACT_TEMPLATE_PARAMETER] macros.
+[footnote
+*Rationale.*
+The ability to specify the parameter identifier (or tag) namespace is offered because it is offered by __Boost_Parameter__ and it gives programmers greater control.
+However, it should be rarely if ever needed because this library provides the [macro CONTRACT_PARAMETER_TYPEOF] macro.
+]
+Instead programmers are encouraged to use these macros within an enclosing namespace as done by the rest of the examples in this documentation.
+
+For example (see also [file example/named_parameters named_param_identifiers_positive.cpp]):
+
+[named_param_identifiers_positive]
+
+Class invariants, preconditions, and postconditions were also specified in this example.
+
+At the template instantiation and function call site, the specified argument identifiers `NumberArg` and `value_arg` can be used instead of the usual trailing underscore (see also [file example/named_parameters named_param_identifiers_positive.cpp]):
+
+[named_param_identifiers_positive_call]
+
+It is not necessary to specify both the parameter identifier namespace and the argument identifier as they are both and independently optional (see also the __Grammar__ section):
+
+    CONTRACT_TEMPLATE_PARAMETER( (NumberArg) Number )   // Specify only argument identifier.
+    CONTRACT_PARAMETER( namespace(params) value )       // Specify only parameter identifier namespace.
+
+It is recommended to never specify the argument identifiers to have the same names as the parameter identifiers in order to avoid the following usually silent bug (see also [file example/named_parameters named_param_identifiers_failure.cpp]):
+
+[import ../example/named_parameters/named_param_identifiers_failure.cpp]
+[named_param_identifiers_failure]
+
+The call `print(age = 3);` will assign `3` to `f`'s parameter `age` instead than passing `3` as the argument of `print`'s parameter `age`.
+The trailing underscore `_` convention and enclosing the named parameter declaration macros [macroref CONTRACT_PARAMETER] and [macroref CONTRACT_TEMPLATE_PARAMETER] within a namespace make this type of name clashes unlikely.

+
+[section No Variadic Macros]
+
+This section illustrates an alternative syntax, the /sequence syntax/, that can be used on compilers that do not support variadic macros.
+Most modern compilers support [@http://en.wikipedia.org/wiki/Variadic_macro variadic macros] (notably, these include GCC, MSVC, and all __CXX11__ compilers).
+
+[warning
+The sequence syntax presented in this section has not been fully tested yet.
+Future revisions of the library are expected to test and support the sequence syntax more thoroughly (see also [@https://sourceforge.net/apps/trac/contractpp/ticket/58 Ticket 58]).
+]
+
+The sequence syntax uses many extra parenthesis and it is significantly less readable than the comma-separated syntax that we have seen so far.
+Therefore, it is strongly recommended to not use the sequence syntax unless it is absolutely necessary to program contracts that are portable to compilers that do not support variadic macros.
+
+[section Sequence Syntax]
+
+In the rare case that programmers need to use this library on compliers without variadic macros, this library also allows to specify its macro parameters using a __Boost_Preprocessor__ sequence in which tokens are separated using round parenthesis `()`:
+
+    (token1) (token2) ... // All compilers.
+
+Instead of the comma-separated lists that we have seen so far which require variadic macros:
+
+    token1, token2, ... // Only compilers with variadic macros (preferred).
+
+This library detects preprocessor support for variadic macros using the __Boost_Config__ macro `BOOST_NO_VARIADIC_MACROS`.
+__Boost_Config__ defines the `BOOST_NO_VARIADIC_MACROS` only on compilers that do not support variadic macros furthermore programmers can forcefully define this macro also on compilers that support variadic macros.
+When this macro is not defined, this library macros support both the camma-separated and sequence syntax, otherwise only the sequence syntax is supported.
+
+[note
+The same macros accept both syntaxes on compilers with variadic macros and only the sequence syntax on compilers without variadic macros.
+]
+
+For example, the syntax on the left hand side works on all compilers with and without variaidic macros (see also [file example/contracts class_template_vector_seq.cpp], [file example/contracts pushable_seq.hpp], [file example/contracts class_template_vector.cpp], and [file example/contracts pushable.hpp]):
+
+[import ../example/contracts/pushable_seq.hpp]
+[import ../example/contracts/class_template_vector_seq.cpp]
+[table
+[ [Sequence Syntax (all compilers)] [Comma-Separated Syntax (variadic macros only, preferred)] ]
+[ [[pushable_seq]] [[pushable]] ]
+[ [[class_template_vector_seq]] [[class_template_vector]] ]
+]
+
+Note the many extra parenthesis around all tokens within the lists: template parameters `(typename T)`, base classes `(public pushable<T>)`, function parameters `(size_type) count`, all assertions, etc.
+Furthermore, empty lists need to be specified using `(void)` instead of just `void`.
+
+When using the sequence syntax, the macro [macroref CONTRACT_LIMIT_OLDOFS] specifies the maximum number of postconditions sequence elements (instead of the maximum possible number of old value declarations as for variadic macros).
+
+[endsect]
+
+[section Commas and Leading Symbols in Macros]
+
+As we have seen in the __Advanced_Topics__ section, syntactic elements containing unwrapped commas and leading symbols need to be wrapped within extra round parenthesis:
+
+    (::std::map<char, int, std::less<char> >)           // With variadic macros.
+
+However, without variadic macros this is no longer sufficient and the number of commas needs to be explicitly specified using the following syntax:
+[footnote
+*Rationale.*
+Using variadic macros, the preprocessor can automatically determine the number of commas within a tuple but without variadic macros that is no longer possible so programmers must manually specify the number of commas.
+]
+
+    comma(2)(::std::map<char, int, std::less<char> >)   // Without variadic macros.
+
+For example (see also [file example/contracts macro_commas_symbols_integral_map_seq.cpp] and [file example/contracts macro_commas_symbols_integral_map.cpp]):
+
+[import ../example/contracts/macro_commas_symbols_integral_map_seq.cpp]
+[table
+[ [Sequence Syntax (all compilers)] [Comma-Separated Syntax (variadic macros only, preferred)] ]
+[ [[macro_commas_symbols_integral_map_seq]] [[macro_commas_symbols_integral_map]] ]
+]

+[section Release Notes]
+
+This section contains notes on the current and on all previous library releases (in chronological order).
+
+[heading Release 0.4.1]
+
+August 20, 2012
+
+Notes:
+
+# Using non-fix-spaced font in Full Table of Contents section.
+# Added a couple of notes to the documentation.
+# Changed `CONTRACT_MEMBER_BODY(class_type, function_name)` to `class_type::CONTRACT_MEMBER_BODY(function_name)` so the macro can also be used to declare derived classes avoiding using the library syntax even when the base class has contracts.
+
+Release [@http://contractpp.svn.sourceforge.net/viewvc/contractpp/releases/contractpp_0_4_1 files] and [@http://contractpp.svn.sourceforge.net/viewvc/contractpp/releases/contractpp_0_4_1/doc/html/index.html documentation].
+
+[heading Release 0.4.0]
+
+June 4, 2012
+
+Notes:
+
+# Simplified syntax by reducing extra parenthesis to the bare necessary minimum (using some of the preprocessor parsing techniques originally introduced by Boost.LocalFunction).
+# Postcondition old values only copy the old-of expression (e.g., copy just vector size instead of entire vector).
+This improves performance and introduces the `ConstantCopyConstructible` requirement just for the old value expression type (e.g., a vector might not be copyable while its size always is because it is an integral type).
+Removed the `copyable` tag.
+# Body defined outside the macros (so compiler-errors for definitions retain their usual meaning).
+# Added `CONTRACT_CLASS` macro and removed the need to duplicate declaration elements (do not repeat function declaration, do not repeat class name in function declaration, etc).
+# Using `_TPL` macros so to reduce compile-time (instead of internally making all templates contract functions so to use `typename` freely).
+# Overloading no longer requires unique parameter names.
+# Added C++11-like virtual specifiers.
+# Added constant assertions plus constant-expressions for select assertion if-conditions and for loop variants.
+# Added named and deduced parameters.
+# Added concept checking.
+# Removed the interface to use the library without the macro (programmers were required to write too much boiler-plate code for the non-macro interface to be actually usable, plus supporting both the macro and non-macro interfaces limited what the macros could do).
+
+Release [@http://contractpp.svn.sourceforge.net/viewvc/contractpp/releases/contractpp_0_4_0 files] and [@http://contractpp.svn.sourceforge.net/viewvc/contractpp/releases/contractpp_0_4_0/doc/html/index.html documentation].
+
+[heading Release 0.3.490]
+
+March 7, 2010
+
+Notes:
+
+# Added support and examples for `volatile`, `auto`, `explicit`, `export`, `extern`, `friend`, `inline`, `struct`, and `throw` (for exception specifications).
+# Documented that `union` cannot be contracted.
+
+Release [@http://contractpp.svn.sourceforge.net/viewvc/contractpp/releases/contractpp_0_3_490 files] and [@http://contractpp.svn.sourceforge.net/viewvc/contractpp/releases/contractpp_0_3_490/doc/html/index.html documentation].
+
+[heading Release 0.3.469]
+
+February 21, 2010
+
+Notes:
+
+# Removed use of `self`, `variable.now`, and `variable.old` in writing contracts.
+Object `this` and variables are now accessed as usual in member functions.
+`CONTRACT_OLDOF(variable)` is used to access old values in postconditions.
+# Added `(precondition)`, `(postcondition)`, and `(body)` to specify contracts within the function signature sequence.
+If no preconditions then `(precondition) ({...})` is simply omitted from the sequence (same for postconditions, body is mandatory instead).
+For non-void functions, users can name the result argument with `(postcondition) (result-name) ({...})`.
+# Changed contract class template to use same syntax as Boost.Function (i.e., `F` function type).
+# Added support for free functions and static member functions.
+# Added support for subcontracting with multiple inheritance.
+# Added static class invariants which are always checked (also at constructors entry, destructor exit, and by static member functions).
+# Added block invariants and Eiffel-like loop variants.
+# Added handlers to customize action on contract failure (default to `std::terminate()`).
+# Removed feature for automatic contract documentation using Doxygen (this is not compatible with added `(precondition)`, `(postcondition)`, and `(body)` because Doxygen preprocessor is not capable to handle Boost.Preprocessor sequences).
+# Rewritten entire documentation (now using Boost.QuickBook instead of Doxygen).
+
+Release [@http://contractpp.svn.sourceforge.net/viewvc/contractpp/releases/contractpp_0_3_469 files] and [@http://contractpp.svn.sourceforge.net/viewvc/contractpp/releases/contractpp_0_3_469/doc/html/index.html documentation].
+
+[heading Release 0.2.190]
+
+November 21, 2009
+
+Notes:
+
+# Compiled using both GCC (Linux and Cygwin) and MSVC (Windows XP).
+# Required to use void to specify empty function argument list.
+This is to comply with C++03 standard that does not allow to pass empty macro parameters so it does not support empty preprocessor sequences `()`.
+
+Release [@http://contractpp.svn.sourceforge.net/viewvc/contractpp/releases/contractpp_0_2_190 files] and [@http://contractpp.svn.sourceforge.net/viewvc/contractpp/releases/contractpp_0_2_190/doc/html/index.html documentation].
+
+[heading Release 0.1.126]
+
+June 17, 2009
+
+Notes:
+
+# Completed first documentation draft.
+
+Release [@http://contractpp.svn.sourceforge.net/viewvc/contractpp/releases/contractpp_0_1_126 files] and [@http://contractpp.svn.sourceforge.net/viewvc/contractpp/releases/contractpp_0_1_126/doc/html/index.html documentation].

+[section Tutorial]
+
+This section explains how to program contracts using this library.
+See the __Grammar__ section for a complete guide on this library syntax.
+
+[section Free Functions]
+
+Consider the following free function `postinc` which performs a post-increment on its parameter (see also [file example/contracts no_contract_postinc.cpp]):
+
+[import ../example/contracts/no_contract_postinc.cpp]
+[no_contract_postinc]
+
+Let's now program the function declaration using the [macroref CONTRACT_FUNCTION] macro but without programming the contract yet (see also [file example/contracts no_pre_post_postinc.cpp]):
+
+[import ../example/contracts/no_pre_post_postinc.cpp]
+[no_pre_post_postinc]
+
+All necessary header files for this library are included by `#include <contract.hpp>` (see also the __Getting_Started__ section).
+
+The function body is programmed outside the library macro.
+Therefore, while this library alters the function declaration syntax, it does not change the syntax used to implement the function.
+
+The function name `(postinc)` must always be wrapped within parenthesis so it can be passed to this library macros.
+
+The function result and parameter types must be wrapped within parenthesis unless they are fundamental types containing no symbol (symbols are tokens different from the alphanumeric tokens `a-z`, `A-Z`, `0-9`).
+In this example, the result type `int const` is a fundamental type and it contains no symbol so the parenthesis around it `(int const)` are allowed but not required.
+[footnote
+In the examples presented in this documentation, extra parenthesis are in general avoided unless strictly required (for example, extra parenthesis around fundamental types containing no symbol `void`, `bool`, `unsigned int const`, etc are always omitted).
+In the authors' opinion, the syntax is more readable with lesser parenthesis.
+However, other programmers might find it more readable to always specify extra parenthesis around result and parameter types for consistency even when they are not strictly required.
+]
+Instead, the parameter type `int&` is a fundamental type but it contains the reference symbol `&` so it must be wrapped within parenthesis `(int&)`.
+

+In general, every token which is not a known keyword (`int` is a known keyword but the function name is not) or that contains a non-alphanumeric symbol (e.g., `int&`) must be wrapped within round parenthesis `(...)` unless it is the very last token of a given syntactic element (e.g., the function parameter name `value` is the last token of the parameter declaration).
+[footnote
+*Rationale.*
+This library uses preprocessor meta-programming to parse declarations and contracts of classes and functions.
+The preprocessor cannot parse a token if it is not known a priori or if it contains symbols, unless such a token is wrapped within round parenthesis `()`.
+For example, the function name is arbitrary, it cannot be known a priori, so it must always be wrapped within parenthesis.
+If a type is a fundamental type then it is known a priori (because it is composed of known C++ keywords `int`, `const`, `unsigned`, etc), and if the fundamental type also contains no symbols (`&`, `*`, etc) then the parenthesis around such a type are optional.
+]
+
+See the __Grammar__ section for more information.
+]
+
+Each function parameter must always specify both its type and its name (parameter names can instead by omitted in usual C++ declarations).
+[footnote
+*Rationale.*
+It would be possible to modify the library syntax to make parameter names optional but that will complicate the library implementation without adding any feature for programmers.
+]
+As usual, additional parameters can be specified separated by commas `,` on compilers that support variadic macros (these include most modern compilers, MSVC, GCC, and all __CXX11__ compilers, see the __No_Variadic_Macros__ section for compilers that do not support variadic macros).
+The configuration macro [macroref CONTRACT_CONFIG_FUNCTION_ARITY_MAX] indicates the maximum number of function parameters that can be specified.
+An empty parameter list must be specified using `void` (this is similar to the usual C++ syntax that allows to declare a function with no parameter using [^['result-type function-name ]]`( void )`).
+[footnote
+*Rationale.*
+Unfortunately, it is not possible to specify an empty parameter list simply as [^['result-type function-name ]]`( )` because the preprocessor can only parse `( )` if empty macro parameters are supported.
+Empty macro parameters together with variadic macros where added to __C99__ and the preferred syntax of this library uses variadic macros.
+However, not all compilers (notably MSVC) that support variadic macros also correctly support empty macro parameters so `( void )` is always used instead of `( )` to increase portability.
+]
+Default parameter values can be specified using `, default `[^['default-value]] immediately following the parameter name.
+The storage classifiers `auto` and `register` can be specified as usual as part of the parameter type.
+[footnote
+Note that the `auto` storage classifier in deprecated by __CXX11__ so it should be used with the usual care when writing programs that should be portable from __CXX03__ to __CXX11__.
+]
+Functions can be overloaded by specifying different parameter types and they can recursively call themselves as usual.
+
+For example, the following function `postinc` is overloaded to work on `long` instead of `int` numbers, it is implemented using recursion, it increments the specified number by `offset` which is stored into a register variable and it has a default value of `1` (see also [file example/contracts params_postinc.cpp]):
+
+[import ../example/contracts/params_postinc.cpp]
+[params_postinc]
+[params_postinc_call]
+
+Function and array types cannot be directly used as function parameter types within the contract macros but extra `typedef` declarations can be used to workaround this limitation (for multi-dimensional arrays, the maximum number of supported array dimensions is specified by the [macroref CONTRACT_CONFIG_ARRAY_DIMENSION_MAX] macro).
+For example (see also [file example/contracts params_funcptr_array_apply.cpp]):
+
+[import ../example/contracts/params_funcptr_array_apply.cpp]
+[params_funcptr_array_apply]
+[params_funcptr_array_apply_call]
+
+Spaces and new-lines make no syntactical difference and they can be used freely within this library macros.
+[footnote
+An MSVC preprocessor bug requires to use at least one space or newline to separate a parameter name from its type even when the parameter type is wrapped within parenthesis.
+]
+The following aesthetic conventions are followed in this documentation (because the authors think they improve readability):
+
+# Round parenthesis are spaced when a list of tokens is expected (e.g., the function parameter list): `( `[^['token1]]` )`, `( `[^['token1]]`, `[^['token2]]` )`, `( `[^['token1]]`, `[^['token2]]`, `[^['token3]]` )`, etc.
+# Round parenthesis are not spaced when only a single token is expected (e.g., the function name): `(`[^['token]]`)`.
+
+[endsect]
+
+[section Preconditions]
+
+Let's program the preconditions of `postinc` (see also [file example/contracts pre_only_postinc.cpp]):
+    
+[import ../example/contracts/pre_only_postinc.cpp]
+[pre_only_postinc]
+
+In this example, the preconditions assert only one boolean condition but additional boolean conditions can be listed separated by commas `,`.
+Preconditions are automatically checked by the library when the `postinc` function is called, immediately before the body is executed (i.e., at function /entry/).
+See also the __Free_Function_Calls__ section.
+
+Contracts are supposed to check but not to modify the state of the program (see the __Constant_Correctness__ section).
+Therefore, this library  evaluates all contract conditions in constant-correct context.
+Specifically, in this example the type of `value` type is automatically promoted from `int&` to `int const&` within the preconditions and an attempt to modify `value` within the preconditions will correctly generate a compile-time error.
+
+[endsect]
+
+[section Postconditions (Result and Old Values)]
+
+Let's program the postconditions of `postinc` completing the contract (see also [file example/contracts post_also_postinc.cpp]):
+
+[import ../example/contracts/post_also_postinc.cpp]
+[post_also_postinc]
+
+Postconditions are automatically checked by the library when the `postinc` function is called, immediately after the body is executed but only if the body does not throw an exception (i.e., at function /normal exit/).
+See also the __Free_Function_Calls__ section.
+
+Postconditions can access the function return value by declaring a variable of type `auto` 
+[footnote
+*Rationale.*
+The __CXX11__ `auto` declaration syntax was adopted for postcondition return value declarations however this library knows the result type because it is specified in the function declaration within the macros so no type deduction is actually used to implement auto declarations of return values.
+Similarly, the __CXX11__ `auto` declaration syntax was adopted for postcondition old value declarations however this library deduces the type of old value expressions using __Boost_Typeof__ so no __CXX11__ feature is actually needed (in this case programmers can optionally specify the old value type so to not use __Boost_Typeof__ as explained in the __Advanced_Topics__ section).
+]
+and assigning it to the `return` keyword (the variable name is arbitrary but `result` is often used).
+
+Postconditions can also access the /old value/ that an expression had just before the body was executed.
+This is done by declaring a variable of type `auto` and assigning it to [macroref CONTRACT_OLDOF] [^['expression]] (the variable name is arbitrary but the `old_` prefix is often used).
+Before executing the function body, the library automatically copies (once) the value of the specified expression into a variable with the specified name which is then made available to the postconditions.
+Therefore, the type of an old value expression must have a copy constructor (or, more precisely, it must be be __ConstantCopyConstructible__), otherwise the library will generate a compile-time error.
+The parenthesis around the expression passed to the [macroref CONTRACT_OLDOF] macro are allowed but not required (in this example, `CONTRACT_OLDOF(value)` could have been equivalently used instead of `CONTRACT_OLDOF value` but the latter was preferred because of lesser parenthesis).
+In this sense, the syntax of the `CONTRACT_OLDOF` macro resembles the syntax of the `sizeof` operator which also allows but does not require parenthesis when applied to value expressions (i.e., `sizeof value` and `sizeof(value)` are both valid).
+[footnote
+*Rationale.*
+This is also the syntax specified by __N1962__ for the `oldof` operator which is the equivalent of the `CONTRACT_OLDOF` macro.
+]
+(The maximum number of supported and possible old value declarations is specified by the [macroref CONTRACT_CONFIG_OLDOF_MAX] and [macroref CONTRACT_LIMIT_OLDOFS] macros respectively.)
+
+Postconditions always access result and old values in constant-correct context so that contracts cannot modify the state of the program (see the __Constant_Correctness__ section).
+
+In general, it is recommended to specify multiple assertions separated by commas and not group them together into a single condition using the operator `and` (or `&&`).
+This is because if assertion conditions are programmed together using `and` then it will not be clear which assertion condition actually failed in case the contract is broken.
+For example, if in the code above we programmed one single postcondition `(value == old_value + 1) and (result == old_value)` then in case the postcondition failed we would not know which condition failed `value == old_value + 1` or `result == old_value`.
+
+[note
+All tokens must be specified in the fixed order listed in the __Grammar__ section (it is not possible to specify postconditions before preconditions, `volatile` before `const` for member functions, etc).
+[footnote
+*Rationale.*
+This library macros could have been implemented to allow to mix the order of some tokens (preconditions and postconditions, `volatile` and `const`).
+However, that would have complicated the macro implementation without any added functionality for the user.
+]
+]
+
+[endsect]
+
+[section Classes and Class Invariants]
+
+Consider the following class `ivector` which is a vector of integers with a constructor, destructor, and the `push_back` member function (see also [file example/contracts no_contract_ivector.cpp]):
+
+[import ../example/contracts/no_contract_ivector.cpp]
+[no_contract_ivector]
+
+Let's program the class declaration and the class invariants using the [macroref CONTRACT_CLASS] and [macroref CONTRACT_CLASS_INVARIANT] macros respectively (see also [file example/contracts class_ivector.cpp]):
+
+[import ../example/contracts/class_ivector.cpp]
+[class_ivector_classinv]
+
+A class must always be declared using the [macroref CONTRACT_CLASS] macro in oder to later be able to program contracts for its constructors, destructor, and member functions.
+Similarly to function names, the class name must always be wrapped within parenthesis `(ivector)` (because the class name is not a known keyword and it is not the last element of the class declaration syntax as base classes and other elements can be specified).
+Only constructors, destructors, and member functions that are public check the class invariants while the ones that are either protected or private do not (see the __Contract_Programming_Overview__ section).
+The class invariant must always be specified for a class declared using the [macroref CONTRACT_CLASS] macro and it must appear at the very beginning of the class definition (no statement can precede the [macroref CONTRACT_CLASS_INVARIANT] macro, not even a `typedef` or a `friend` declaration).
+If a class has no class invariant, the class invariants must be specified `void`:
+
+    CONTRACT_CLASS(
+        class (ivector)
+    ) {
+        CONTRACT_CLASS_INVARIANT( void ) // No class invariant.
+
+        // ...
+
+Using the same macro, this library also allows to specify contracts for `struct`:
+[footnote
+*Rationale.*
+There is no need for a `CONTRACT_STRUCT` macro because this library macros can parse the class declaration and distinguish between the `struct` and `class` specifiers.
+]
+
+    CONTRACT_CLASS(
+        struct (ivector) // Structs with contracts.
+    ) {
+        // ...
+
+The usual differences between `struct` and `class` also apply when this library is used (i.e., default member and inheritance access levels are `public` for `struct` and `private` for `class`).
+
+[note
+Unfortunately, this library does not allow to specify contracts for `union`.
+[footnote
+*Rationale.*
+The authors have not fully investigated if this library could be extended to specify contracts for unions.
+It is possible that future revisions of this library will support contracts for unions (see also [@http://sourceforge.net/apps/trac/contractpp/ticket/50 Ticket 50]).
+]
+]
+
+No contracts are checked (not event the class invariants) when a data member is accessed directly so it might be best for both classes and structs to have no non-constant public data member (but access all data members via appropriate member functions that can check the class and sturct contracts).
+
+[endsect]
+
+[section Constructors]
+
+Let's program the `ivector` class constructor and its contract using the [macroref CONTRACT_CONSTRUCTOR] macro (see also [file example/contracts class_ivector.cpp]):
+
+[class_ivector_constructor]
+
+Constructor, destructor, and member function declarations must always repeat their access level `public`, `protected`, or `private`
+[footnote
+*Rationale*
+This library needs to know each member access level because in Contract Programming only public members are supposed to check class invariants while protected and private members only check preconditions and postconditions but not the class invariants.
+Unfortunately, in C++ it is not possible for a member to introspect its access level using template meta-programming.
+Therefore, this library requires the access level to be specified within the macros and it uses preprocessor meta-programming to detect it.
+Furthermore, given that the access level is has to be specified, the [macroref CONTRACT_FUNCTION] macro also uses it to differentiate between free and member functions so no additional macro `CONTRACT_MEMBER` is needed.
+]
+which is specified without the usual trailing column symbol `:`.
+(This use of `public`, `protected`, and `private` resembles __Java__'s syntax.)
+
+The constructor name `(ivector)` and the non-fundamental parameter type `(size_type)` must be wrapped within parenthesis (because they are not known keywords and they are not at the end of a syntactic element).
+
+Member initializers are programed as a comma-separated list but using the specifier [^initialize( /expression1/, /expression2/, ... )] instead of the usual column symbol [^: /expression1/, /expression2/, ...].
+When specified, they must appear at the very end of constructor declarations (after both preconditions and postcondition if present).
+[footnote
+*Rationale.*
+Member initializers are specified after the preconditions and postconditions because they are part of the constructor definition while preconditions and postconditions are part of the constructor declaration.
+]
+Unfortunately, when member initializers are specified, the constructor body must be defined together with its declaration and contract (see the __Forward_Declarations_and_Body_Definitions__ section).
+
+There is no object before the constructor body is executed, therefore this library will generate a compile-time error if either preconditions or postcondition old value expressions try to access the object `this`.
+For the same reason, only static class invariants are checked at entry of public constructors (non-static class invariants are checked at public constructor normal exit but not at entry).
+Finally, preconditions are checked before member initializers are executed (so the initializers can rely on preconditions for validating constructor arguments).
+See also the __Constructor_Calls__ section.
+
+[endsect]
+
+[section Destructors]
+
+Let's program the `ivector` class destructor using the [macroref CONTRACT_DESTRUCTOR] macro (see also [file example/contracts class_ivector.cpp]):
+
+[class_ivector_destructor]
+
+The destructor access level `public`, `protected`, or `private` must always be specified.
+The destructor name `(~ivector)` must be wrapped within parenthesis.
+The destructor empty parameter list must be specified using `void` (same as for constructors, member functions, and free functions with no parameters).
+
+Destructors have no parameter and there is no object after the destructor body is executed.
+Therefore, destructors cannot specify neither preconditions nor postconditions.
+[footnote
+Future revisions of this library might implement static postconditions for destructors (see the __Destructor_Calls__ section).
+]
+However, it is still necessary to ontract (at least public) destructors so they check static and non-static class invariants at entry, and non-static class invariants at exit.
+See also the __Destructor_Calls__ section.
+
+[important
+Only members declared using this library macros check the class invariants.
+Therefore, at least all public members of a class with non-empty class invariants should be declared using this library macros even when they have no preconditions and no postconditions so that they check the class invariants (that is the case for public destructors).
+]
+
+In general, there is no need to use this library macros to declare free functions, constructors, destructors, and member function only when:
+
+# A free function has no preconditions and no postconditions.
+# A private or protected constructor, destructor, or member function has no preconditions and no postconditions (regardless of class invariants because private and protected members never check class invariants).
+# A public constructor, destructor, or member function has no preconditions, no postconditions, and its class has no class invariants.
+
+[endsect]
+
+[section Member Functions]
+
+Let's program the member function `ivector::push_back` and its contract using the [macroref CONTRACT_FUNCTION] macro (see also [file example/contracts class_ivector.cpp]):
+
+[class_ivector_member]
+
+The member function access level `public`, `protected`, or `private` must always be specified.
+The member function name `(push_back)` must be wrapped within parenthesis.
+The member function result type `void` and parameter type `int const` can but do not have to be wrapped within parenthesis (because they are both fundamental types containing no symbol).
+
+Public non-static member functions check static and non-static class invariants at both entry and exit.
+Preconditions are checked at entry and postconditions are checked at normal exit.
+Both preconditions and postconditions can access the object and the member function parameters in constant-correct context.
+Postconditions can declare return and old value variables (again, in contract-correct context).
+See also the __Member_Function_Calls__ section.
+
+[note
+Contracts are most useful when the assertions only use public members that are accessible from the caller so the caller can properly verify and use the contract.
+In particular, preconditions of a member function or constructor that use non-public members are essentially incorrect because they cannot be verified by the caller before calling the function (in fact, __Eiffel__ generates a compile-time error in this case).
+
+This library leave it up to programmers to only use public members when programming contracts and especially when programming preconditions (see the __Specification_vs__Implementation__ section).
+]
+
+[endsect]
+
+[section Inheritance and Subcontracting]
+
+Consider the following class `unique_identifiers` which is a collection of unique integral identifiers (see also [file example/contracts subcontract_identifiers.cpp]):
+
+[import ../example/contracts/subcontract_identifiers.cpp]
+[subcontract_identifiers_unique]
+
+Reading the contracts we can understand the semantics of the class operation (even if we do not consult the class implementation):
+
+# The collection is constructed with zero size as specified by the constructor postconditions.
+Consistently, the class invariants assert that the class size must never be negative (but it can be zero).
+# The member function `unique_identifiers::add` allows to add an integral identifier to the collection.
+The preconditions assert that the specified identifier must not already be part of the collection making sure that duplicate identifiers are never added.
+# If the specified identifier was not already part of the collection (`old_found` is `false`) then the postconditions assert that the identifier is added and consequently that the size of the collection increased by one.
+Note that both postconditions are trivially `true` if instead the identifier was already part of the collection (`old_found` is `true`).
+We call these type of assertions that are "guarded" by an activation condition /select assertions/ (here we have used the C++ ternary operator `?:` to program select assertions, the __Advanced_Topics__ section will introduce an alternative construct for select assertions).
+
+Let's assume that we want to derive from `unique_identifiers` another type of collection `duplicate_identifiers` which instead allows to add duplicate identifiers (see also [file example/contracts subcontract_identifiers.cpp]):
+
+[subcontract_identifiers_duplicate]
+
+The derived class `duplicate_identifiers` publicly inherits from the base class `unique_identifiers` using the specifier [^extends( /base1/, /base2/, ... )] instead of the usual column symbol [^: /base1/, /base2/, ...]. (This use of `extends` resembles __Java__'s syntax.)
+As usual, the inheritance access level `public`, `protected`, or `private` is optional and it defaults to `public` for `struct` and to `private` for `class`.
+Virtual base classes can also be specified but `virtual` must always be specified after the inheritance access level `public`, `protected`, or `private` if present.
+Multiple base classes (`base1`, `base2`, etc) can be specified for multiple-inheritance (the configuration macro [macroref CONTRACT_CONFIG_INHERITANCE_MAX] indicates the maximum number of base classes that can be specified).
+
+[note
+This library automatically subcontracts the derived class when one or more base classes are specified (see the __Contract_Programming_Overview__ section).
+]
+
+Let's assume that a `duplicate_identifers` object is constructed with identifier `123` and that we try to add the identifier `123` again:
+
+[subcontract_identifiers_duplicate_add]
+
+Reading both the derived and base class contracts, we can understand the semantics of the derived class operation (even if we do not consult the base and derived class implementations):
+
+# The `duplicate_identifiers` constructor creates a collection with size one as specified by the constructor postconditions.
+Therefore, the `duplicate_identifiers` class invariants assert that size is always positive.
+Subcontracting automatically checks the `unique_identifiers` base class invariants in __logic_and__ with the `duplicate_identifiers` derived class invariants thus class invariants can only be strengthened by derived classes (this is necessary because the derived class can be used whenever the base class is used therefore the derived class must satisfy the base class invariants at all times, see also the __substitution_principle__ and the __Contract_Programming_Overview__ section).
+# Subcontracting automatically checks the `unique_identifiers::add` overridden preconditions in __logic_or__ with the `duplicate_identifiers::add` overriding preconditions thus preconditions can only be weakened by overriding member functions (this is necessary because the overriding member function can be called under the conditions for which the overridden function is called, see also the __substitution_principle__ and the __Member_Function_Calls__ section).
+Indeed, in this example the `unique_identifiers::add` preconditions fail (because `123` is already in the collection) but the `derived_identifiers::add` preconditions pass so the __logic_or__ of the two sets of preconditions passes and the call `ids.add(123)` is a valid call.
+# Subcontracting automatically checks the `unique_identifiers::add` overridden postconditions in __logic_and__ with the `duplicate_identifiers::add` overriding postconditions thus postconditions can only be strengthen by overriding member functions (this is necessary because the overriding function can be called in any context in which the overridden function is called, see also the __substitution_principle__ and the __Member_Function_Calls__ section).
+Indeed, in this example the `unique_identifiers::add` postconditions pass because the identifier `123` was already added (`old_found` is `true`) and `unique_identifiers::add` select assertions trivially return `true`.
+The `duplicate_identifiers::add` postconditions are then checked in __logic_and__ and they correctly assert that the collection size did not change given that `123` was already added.
+Therefore, the call `ids.add(123)` is valid but adds no identifier.
+
+Finally, note that within the body of overriding functions it is necessary to use the [macroref CONTRACT_MEMBER_BODY] macro to call the overridden function as in `unique_identifiers::CONTRACT_MEMBER_BODY(add)(id)`.
+
+[warning
+Unfortunately, invoking the overridden function from within the overriding function body without using [macroref CONTRACT_MEMBER_BODY] results in infinite recursion.
+[footnote
+*Rationale*.
+In this case, the library implementation will recursively check contracts of the overriding function forever (in all other cases, this library is able to avoid infinite recursions due to contract checking).
+]
+This limitation might be removed in future revisions of this library (see also [@https://sourceforge.net/apps/trac/contractpp/ticket/46 Ticket 46]).
+]
+
+[endsect]
+
+[section Class Templates]
+
+Let's program a class template `vector` similar to the class `ivector` we have seen before but that works on a generic value type `T` and not just on `int` (see also [file example/contracts class_template_vector.cpp] and [file example/contracts pushable.hpp]):
+
+[import ../example/contracts/class_template_vector.cpp]
+[class_template_vector]
+
+(The specifications of the code in this example are not fully programmed, in particular concepts, see the __Concepts__ section, and assertion requirements, see the __Advanced_Topics__ section, have been omitted for simplicity.)
+
+Note that templates are declared using the specifier `template( typename T, ... )` which uses round parenthesis instead of the usual angular parenthesis `template< typename T, ... >`.
+However, after a template is declared using round parenthesis, angular parenthesis are used as usual to instantiate the template (e.g., the base class `pushable<T>`).
+
+[important
+Within a type-dependent scope (e.g., within the class template of the above example) the special macros with the `_TPL` postfix must be used instead of the macros we have seen so far.
+[footnote
+*Rationale.*
+The library must know if the enclosing scope is a template so it knows when to prefix nested type expressions with `typename` (because __CXX03__ does not allow to use `typename` outside templates).
+This constraints could be relaxed on future revisions of this library for __CXX11__ compilers (because __CXX11__ allows to use `typename` more freely).
+Earlier versions of this library did not require to use the special `_TPL` macros within templates because the library internally implemented every contracted function using a template function, possibly with dummy template parameters, even if the original function was not a template so `typename` could always be used by the library.
+The dummy template parameters were hidden to the user so this approach did not change the user API and had the benefit of not requiring the `_TPL` macros.
+However, this approach increased compilation time because of the extra templates that it introduced so the current revision of the library uses the `_TPL` macros.
+]
+(The same applies to function templates, see below.)
+]
+
+In the example above, the enclosing class template `vector` is not declared using the [macroref CONTRACT_CLASS_TPL] macro because its enclosing scope is not type-dependent (it is the global namespace).
+Within such a class template however, all contract macros must use the `_TPL` postfix so [macroref CONTRACT_CLASS_INVARIANT_TPL], [macroref CONTRACT_CONSTRUCTOR_TPL], [macroref CONTRACT_DESTRUCTOR_TPL], and [macroref CONTRACT_FUNCTION_TPL] must be used to specify class invariants, declare constructors, declare the destructor, and declare member functions respectively.
+In general, the [macroref CONTRACT_CLASS_TPL] macro is used when declaring a class nested within a class template (see the __Advanced_Topics__ section).
+
+This libraries supports all the different kinds of template parameters that C++ supports: type template parameters, value template parameters, and template template parameters.
+
+* Type template parameters can be prefixed by either `typename` or `class` as usual, `typename A` or `class C`.
+* The type of value template parameters must be wrapped within parenthesis `(A) D` but the parenthesis are optional for fundamental types that contain no symbol `int B`.
+* Template template parameters use round parenthesis for their template specifier but then their inner template parameters are specified using the usual C++ syntax `template( typename X, template< ... > class Y, ... ) class E`.
+
+Default template parameters are specified using `, default `[^['default-value]] right after the template parameter declaration.
+For example (see also [file example/contracts template_params.cpp]):
+
+[import ../example/contracts/template_params.cpp]
+[template_params_class]
+
+Finally, the syntax `template( void )` is used instead of the usual `template< >` to specify a template with no template parameters (this is typically used for template specializations, see the __Advanced_Topics__ section).
+
+[endsect]
+
+[section Function Templates]
+
+Let's program a function template `postinc` similar to the function `postinc` that we have seen before but that works on a generic type `T` and not just on `int` (see also [file example/contracts function_template_postinc.cpp]):
+
+[import ../example/contracts/function_template_postinc.cpp]
+[function_template_postinc]
+
+(The specifications of the code in this example are not fully programmed, in particular concepts, see the __Concepts__ section, and assertion requirements, see the __Advanced_Topics__ section, have been omitted for simplicity.)
+
+Type, value, and template template parameters are specified for function templates using the same syntax used for class template parameters, for example (see also [file example/contracts template_params.cpp]):
+
+[template_params_function]
+
+Note that as usual, function templates cannot have default template parameters in __CXX03__.
+
+[endsect]
+
+[section Forward Declarations and Body Definitions]
+
+This library supports contracts for classes and functions that have forward declarations.
+Furthermore, the function body definition can be deferred and separated from the function declaration and its contracts.
+For example (see also [file example/contracts body_natural.hpp], [file example/contracts body_natural_impl.hpp], and [file example/contracts body_natural.cpp]):
+
+[import ../example/contracts/body_natural.hpp]
+[body_natural]
+
+In this example, the class `natural` and the function `less` are first forward declared and later declared.
+Note that the contracts can be specified only once and together with the class or function declaration (not with the forward declarations that can be many).
+
+[important
+This library forces to specify contracts with the function and class declarations and not with their definitions.
+This is correct because contracts are part of the program specifications (declarations) and not of the program implementation (definitions), see also the __Specification_vs__Implementation__ section.
+]
+
+Note that as usual in C++, not all functions need to be defined when they are first declared.
+In this example, `less` and `natural::get` are defined together with their declarations and contracts while the other function bodies are defined separately.
+
+The definitions of the free function `greater`, the constructor `natural::natural`, the destructor `natural::~natural`, and the member function `natural::equal` are deferred and separated from their declarations and contracts.
+In fact, a semicolon `;` is specified right after the contract declaration macros instead of programming the function bodies.
+As usual in C++, the semicolon `;` indicates that the function body definition is deferred and it will appear at some other point in the program (often in a =.cpp= file that can be compiled separately).
+In this example, the deferred functions are templates or template members therefore the definitions where programmed in a header file that must be made available when the template declarations are compiled (see also [file example/contracts body_natural_impl.hpp]):
+[footnote
+In principle, this library supports `export` templates that can be used to program template definitions separately from their declarations and in files that can be pre-compiled.
+However, `export` templates are not supported by most __CXX03__ compilers (in fact, [@http://www.comeaucomputing.com/4.0/docs/userman/export.html Comeau] might be the  only compiler that supports them), they were removed from __CXX11__, and they are an untested feature of this library.
+Instead of using `export` templates, it is common practise in C++ to program both template declarations and definitions together so they can be compiled correctly.
+In this example, the authors have used a separate header file `..._impl.hpp` to logically separate template declarations and definitions but the header is included at the bottom of the declaration header file so the definitions are always available together with their declarations.
+]
+
+[import ../example/contracts/body_natural_impl.hpp]
+[body_natural_impl]
+
+The usual C++ syntax is used to define the bodies (in fact this library only alters the syntax of class and function declarations but not the syntax of their definitions).
+However, free function, constructor, destructor, and member function names must be specified using the macros [macroref CONTRACT_FREE_BODY], [macroref CONTRACT_CONSTRUCTOR_BODY], [macroref CONTRACT_DESTRUCTOR_BODY], and [macroref CONTRACT_MEMBER_BODY] respectively.
+[footnote
+*Rationale.*
+Four different body macros are needed because contracts are disabled differently for the different type of functions.
+For example, disabling preconditions and postconditions turns off contracts for free functions but not for member functions, disabling class invariants turns off contracts for destructors but not for constructors, etc.
+]
+The free and member body macros take one parameter which is the function name.
+The constructor and destructor body macros take two parameters that are the fully qualified class type (including eventual template parameters as usual) and the class name which must be prefixed by the tilde symbol `~` for destructors as usual.
+[footnote
+Some compilers accept to repeat template parameter names in the constructor and destructor names.
+However, this is not __CXX03__ compliant (and, for example, it was fixed in more recent versions of GCC) therefore programmers are advised to specify the template parameter names only for the class type and not for the constructor and destructor names (this is also why the macros must take a second parameter with the class name instead of just the class type parameter).
+]
+The class type parameter must be wrapped within extra parenthesis like in this example but only if it contains multiple template parameters (because these use unwrapped commas which cannot be passed within macro parameters, see the beginning of the __Advanced_Topics__ section).
+
+In this example, it was possible to separate the constructor body definition because the constructor did not specify member initializers.
+
+[warning
+Unfortunately, when member initializers are specified, the macro [macroref CONTRACT_CONSTRUCTOR_BODY] cannot be used, the constructor body definition cannot be deferred, and the constructor body must be defined together with the constructor declaration and its contract inside the class definition.
+[footnote
+*Rationale.*
+This limitation comes from the fact that __CXX03__ does not support delegating constructors.
+If member initializers are specified within the contract, the deferred body will not compile when contract compilation is turned off by the configuration macros.
+If instead member initializers are specified with the deferred body definition, the deferred body will not compile when contract compilation is turned on by the configuration macros.
+There is no way to reconcile these two conditions without delegating constructors, so definitions cannot be deferred for constructors that specify member initializers.
+This limitation could be removed in future revisions of this library for __CXX11__ compilers that support delegating constructors (see also [@http://sourceforge.net/apps/trac/contractpp/ticket/51 Ticket 51].

+[section Virtual Specifiers]
+
+This section explains how to use this library to program virtual specifiers `final`, `override`, and `new`.
+Virtual specifiers are part of the program specifications because they enforce inheritance constraints at compile-time and therefore they are within the scope of this library.
+
+[important
+This library implements virtual specifiers for __CXX03__ and without using any __CXX11__ feature.
+[footnote
+This library declares special member functions to ["tag] virtual traits of a given member function in a base class (if it is `virtual`, `final`, etc).
+Then template meta-programming introspection is used by the derived class to inspect virtual trait in its base classes and generate compiler errors if the virtual specifiers are not satisfied.
+These techniques do not use any __CXX11__ feature however, future revisions of this library might use __CXX11__ native support for virtual specifiers so to eliminate the extra compilation time required by template meta-programming introspection and correct a number of bugs associated with the current implementation of virtual specifiers in this library (see also [@http://sourceforge.net/apps/trac/contractpp/ticket/53 Ticket 53], [@http://sourceforge.net/apps/trac/contractpp/ticket/53 Ticket 55], and [@http://sourceforge.net/apps/trac/contractpp/ticket/53 Ticket 56]).
+]
+Obviously, virtual specifiers are supported only if both the base and derived classes and member functions in question are declared using this library macros (otherwise this library has no control over usual C++ declarations).
+]
+
+The examples presented in this section are rather simple (and they do not define virtual destructors for brevity).
+These examples only aim to illustrate the syntax of this library virtual specifiers and not to make a case about the utility of these specifiers.
+Virtual specifiers were adopted by __CXX11__ and in some form are part of other languages like __Java__, programmers can refer to the web and to the __Examples__ section for more interesting examples.
+
+[section Final Classes]
+
+Final classes cannot be derived, otherwise the compiler will generated an error.
+This library allows to declare a class final by specifying `final` within the [macroref CONTRACT_CLASS] macro after the class name, after template specialization types but before base classes if present (see also the __Grammar__ section).
+
+For example (see also [file example/virtual_specifiers final_class.hpp] and [file example/virtual_specifiers final_class.cpp]):
+
+[import ../example/virtual_specifiers/final_class.hpp]
+[final_class]
+
+If a derived class declared using [macroref CONTRACT_CLASS] attempts to inherit from a final base class, the compiler will generate a compile-time error (this is true only if both the base and derived classes are declared using this library macro [macroref CONTRACT_CLASS]).
+For example, consider the following derived class (see also [file example/virtual_specifiers final_class_error.cpp]):
+
+[import ../example/virtual_specifiers/final_class_error.cpp]
+[final_class_error]
+
+This will generate a compile-time error similar to the following because `x` is final (note that the number of the base class that violates the `final` specifier is reported so it is clear which base class is causing the error also in case of multiple-inheritance):
+
+[pre
+final_class_error.cpp:8 ... ERROR_cannot_extend_final_base_class_number_1 ...
+]
+
+Final class checks are performed at compile-time even when contracts are disabled (using [macroref CONTRACT_CONFIG_NO_PRECONDITIONS], [macroref CONTRACT_CONFIG_NO_POSTCONDITIONS], [macroref CONTRACT_CONFIG_NO_CLASS_INVARIANTS], etc).
+
+[endsect]
+
+[section Final Member Functions]
+
+Final member functions cannot be overridden by derived classes, otherwise the compiler will generate an error.
+This library allows to declare a member function final by specifying `final` within the [macroref CONTRACT_FUNCTION] macro, after the cv-qualifier but before exception specifications if present (see also the __Grammar__ section).
+
+For example (see also [file example/virtual_specifiers final_member.hpp] and [file example/virtual_specifiers final_member.cpp]):
+
+[import ../example/virtual_specifiers/final_member.hpp]
+[final_member]
+
+If a member function of a derived class is declared using [macroref CONTRACT_FUNCTION] and attempts to override a final member function from one of the base classes, the compiler will generate a compile-time error (this is true only if both the overriding and overridden functions are declared using this library macro [macroref CONTRACT_FUNCTION]).
+For example, consider the following derived class (see also [file example/virtual_specifiers final_member_error.cpp]):
+
+[import ../example/virtual_specifiers/final_member_error.cpp]
+[final_member_error]
+
+This will generate a compile-time error similar to the following because `y::f` is final (note that the number of the base class that violates the `final` specifier is reported so it is clear which overridden member function is causing the error also in case of multiple-inheritance):
+
+[pre
+final_member_error.cpp:13 ... ERROR_cannot_override_final_function_from_base_class_number_1 ...
+]
+
+In order to correctly handle overloaded functions, the overriding function and the final function must have the same name, parameter types, and cv-qualifier to generate this error.
+
+Final member function checks are performed at compile-time but only when class invariants are enabled ([macroref CONTRACT_CONFIG_NO_CLASS_INVARIANTS] is left not defined).
+
+[endsect]
+
+[section Overriding Member Functions]
+
+Overriding member functions must override a virtual member function from one or more of the base classes, otherwise the compiler will generate an error.
+This library allows to declare an overriding member function by specifying `override` within the [macroref CONTRACT_FUNCTION] macro, after the cv-qualifier but before the `final` specifier if present (`override` and `final` can be used together, see also the __Grammar__ section).
+
+For example (see also [file example/virtual_specifiers override_member.hpp] and [file example/virtual_specifiers override_member.cpp]):
+
+[import ../example/virtual_specifiers/override_member.hpp]
+[override_member]
+
+If a member function of a derived class is declared using [macroref CONTRACT_FUNCTION] and attempts to override an non-virtual or non-existing member function from one of the base classes, the compiler will generate a compile-time error (this is true only if both the overriding and overridden functions are declared using this library macro [macroref CONTRACT_FUNCTION]).
+For example, consider the following derived class (see also [file example/virtual_specifiers override_member_error.cpp]):
+
+[import ../example/virtual_specifiers/override_member_error.cpp]
+[override_member_error]
+
+This will generate a compile-time error similar to the following because `x::g` is not virtual:
+
+[pre
+override_member_error.cpp:12 ... ERROR_no_base_class_declares_matching_virtual_function_to_override_at_line_12 ...
+]
+
+In order to correctly handle overloaded functions, the overriding function and the overridden virtual function must have the same name, parameter types, and cv-qualifier to /not/ generate this error.
+
+Overriding member function checks are performed at compile-time but only if at least one between preconditions, postconditions, and class invariants is enabled ([macroref CONTRACT_CONFIG_NO_PRECONDITIONS], [macroref CONTRACT_CONFIG_NO_POSTCONDITIONS] and [macroref CONTRACT_CONFIG_NO_CLASS_INVARIANTS] are not all defined at the same time).
+
+[endsect]
+
+[section New Member Functions]
+
+New member functions shall not override member functions from any of the base classes, otherwise the compiler will generate an error.
+This library allows to declare a new member function by specifying `new` within the [macroref CONTRACT_FUNCTION] macro, after the cv-qualifier but before the `final` specifier if present (`new` and `final` can be used together, see also the __Grammar__ section).
+
+For example (see also [file example/virtual_specifiers new_member.hpp] and [file example/virtual_specifiers new_member.cpp]):
+
+[import ../example/virtual_specifiers/new_member.hpp]
+[new_member]
+
+If a new member function of a derived class is declared using [macroref CONTRACT_FUNCTION] but it overrides an existing member function from one of the base classes, the compiler will generate a compile-time error (this is true only if both the overriding and overridden functions are declared using this library macro [macroref CONTRACT_FUNCTION]).
+For example, consider the following derived class (see also [file example/virtual_specifiers new_member_error.cpp]):
+
+[import ../example/virtual_specifiers/new_member_error.cpp]
+[new_member_error]
+
+This will generate a compile-time error similar to the following because `f` was already declared in `x` (note that the number of the base class that violates the `new` specifier is reported so it is clear which overridden member function is causing the error also in case of multiple-inheritance):
+
+[pre
+new_member_error.cpp:12 ... ERROR_matching_virtual_function_already_declared_by_base_class_number_1 ...
+]
+
+In order to correctly handle overloaded functions, the new function and the overridden function must have the same name, parameter types, and cv-qualifier to generate this error.
+
+New member function checks are performed at compile-time but only if at least one between preconditions, postconditions, and class invariants is enabled ([macroref CONTRACT_CONFIG_NO_PRECONDITIONS], [macroref CONTRACT_CONFIG_NO_POSTCONDITIONS] and [macroref CONTRACT_CONFIG_NO_CLASS_INVARIANTS] are not all defined at the same time).

+//    itself can still be modified. This is the way C++ usually uses
+//    pointers for const because eventual modification to the pointer
+//    only have local scope so do not violate const correctness. (The
+//    pointer could be passed as const* const to also prevent
+//    modification to the pointer itself...)

+// WARNING: Unfortunately, this file must use internal implementation details
+// (aux) of Boost.Parameter. This is done to work around Boost.Parameter
+// limitations in supporting constructors that (1) only allow to specify a 
+// single base class taking all named parameters at once in the member
+// initializers, (2) it does not allow to specify the body (so making it not 
+// possible to invoke the contracted function to implement contracts), and (3)
+// force the use of default values in the base constructor implementation away
+// from the actual constructor definition. All these issue are solved here
+// even if at the cost of having to use a macro to access the named parameters
+// within the member initializers (this is because of lack of delegating
+// constructors so parameters must be defined as pointers so they can have
+// null default values in the constructor declaration) but named parameters
+// are accessed as usual in preconditions, postconditions, and body.

+@brief Trait used to determine if a type can be copied for an old value or not.

+A type can be used for a postcondition old value if and only if it can be

+By default, all types that have a constant-correct copy constructor (i.e., that are <c>ConstantCopyConstructible</c>) can be copied by
+@RefClass{contract::copy}.
+
+If a type cannot be copied, an old value declaration using such a type will not
+fail but it will generate an old value that will cause a compile-time error as
+soon as it is used in a contract assertion.
+Therefore, this trait can be used to program assertion requirements for those
+assertions that use old values on generic types that are not always known to be
+copyable.
+This way, the assertions will be disabled by the requirement instead of
+generating a compile-time error when the old values they use cannot be copied.

+Unfortunately, in C++ it is not possible to portably implement a template
+meta-function that checks if a generic type has a constant-correct copy
+constructor (or even just a copy constructor).
+Therefore, the default implementation of this trait is <c>boost::mpl::true_</c>
+for any type <c>OdlofExpressionType</c>.
+This will cause compile-time errors for old value types that cannot be copied
+in which case users can specialize this unary boolean meta-function to inherit
+from <c>boost::mpl::false_</c> for such types.

+RELEASE INSTRUCTIONS
+====================
+
+How to release this library version X.Y.Z from SVN trunk to SourceForge (SF).
+
+1.  PREPARE TO RELEASE
+
+* Make sure all examples and test compiles.
+* Make sure that documentation, release version, and release notes are up-to-date.
+* Make sure that "trunk/index.html" redirects to "releases/contractpp_X_Y_Z/doc/html/index.html".
+
+Commit everything (code, documentation, etc) to SVN trunk.
+
+2.  RELEASE BRANCH
+
+Create a SVN branch for the release X.Y.Z for example from trunk, make sure all code is correctly checked into trunk, then:
+    
+    $ svn cp https://contractpp.svn.sourceforge.net/svnroot/contractpp/trunk https://contractpp.svn.sourceforge.net/svnroot/contractpp/releases/contractpp_X_Y_Z
+
+3.  ZIP FILE
+
+Create a "contractpp_X_Y_Z.zip" file from the release branch (this ZIP file
+should not go in SVN, just uploaded it on SF as explained in the next step):
+
+    $ zip contractpp/release/contractpp_X_Y_Z contractpp_X_Y_Z.zip
+
+4.  UPLOAD ZIP FILE TO SF
+
+Log in to SF website and go to Contract++ page, click Files, then "releases", and then Add File to upload "contract_X_Y_Z.zip".
+Click the information icon ("I" icon on the right-hand-side of the file) and select the newly added file as the "Default Download" for all platform then click Save (the file should now show as the "latest version" on the top of the page and SF will link it to the "Download" from the library documentation).
+
+5.  UPLOAD DOCUMENTATION INDEX.HTML
+
+Using FileZilla connect to the location below and drag-and-drop releases/contract_X_Y_Z/index.html to the project-web/contractpp/htdocs/ localtion:
+
+    Host        web.sourceforge.net
+    Protocol    SFTP
+    Port        22
+    Username    ...
+    Password    ...
+    Upload to   /home/project-web/contractpp/htdocs
+
+The LICENSE_1_0.txt and COPYRIGHT.txt files should be copied to this location also (but they might already be there).
+
+6.  FINAL CHECKS
+
+* Go to the project web http://contractpp.sourceforge.net and check that the latest documentation shows up.
+* Click on "Download" for the documentation and check that contractpp_X_Y_Z.zip is downloaded (correct version).
+
+7.  UPDATE INFORMATION ON SF (IF NEEDED)
+
+Update the information on SF if needed: library release status (pre-alpha, beta, etc), library logo on SF, name, description, feature list, screenshots, etc.
+
