 Would it be possible that more template parameters of boost::any_range get
 a default value?

 It seems like ''Reference'' and ''Difference'' mostly refer to the same
 types. The declaration could look like this:

 {{{
 #!cpp
 template<
             class Value
           , class Traversal
           , class Reference = Value&
           , class Difference = std::ptrdiff_t
           , class Buffer = use_default
         >
         class any_range;
 }}}

 This would also be consistent with boost::iterator_facade.
