#9754: boost::is_function VS compile error (for const operator function)

     Type:  Bugs                                |     Status:  new
Milestone:  To Be Determined                    |  Component:  type_traits
  Version:  Boost 1.55.0                        |   Severity:  Problem
 Keywords:  boost::is_function, compile error   |
------------------------------------------------+-------------------------
 If you try to evaluate boost::is_function on functions that have the same
 signature and one of them are member const operator function, VC++ (10
 through 12) fires compile error:

 Sample minimal code:

 struct Functor {
   void operator()() const {}
   };
 boost::is_function<void()>::value;
 boost::is_function<decltype(Functor().operator())>::value;

 Compiler output:
 1>$(path)\boost\type_traits\is_function.hpp(72): error C2373: 't' :
 redefinition; different type modifiers
 1>          $(path)\boost\type_traits\is_function.hpp(72) : see
 declaration of 't'
 1>          $(path)\boost\type_traits\is_function.hpp(97) : see reference
 to class template instantiation 'boost::detail::is_function_impl<T>' being
 compiled
