For example <code class="computeroutput">BOOST_IDENTITY_TYPE((std::map<int, double>))</code> can be passed as a single macro parameter when instead <code class="computeroutput">std::map<int, double></code> cannot (because it contains a comma not wrapped by round parenthesis so it will be interpreted as two separate macro parameters by the preprocessor).

 Rationale. This is because a local function
 is a functor object declared as a local variable within the enclosing scope.
 Therefore, declaring two local functions with the same name within the
 same enclosing scope declares two local variables with the same name within
 the same scope and that is not allowed in C++.
