9754,boost::is_function VS compile error (for const operator function),Yaroslav Lukyanchuk <yarosladov@…>,John Maddock,"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:
