is_member_function_pointer implementation

Question

I am trying to implement my own is_member_function_pointer and I\'m having trouble with it.

namespace __implementation
{
    // integral_constan

Alternatively

template struct remove_c { typedef T type; };
template struct remove_c { typedef T type; };

template 
struct bool_ { static bool const value = C; };

template
struct is_same : bool_ {};

template
struct is_same : bool_ { };

template >
struct is_function : bool_ {};

struct C { };

template
struct is_function< T, 
   bool_::type const C::*, 
                 typename remove_c::type       C::*>::value> > 
  : bool_ {};

template
struct is_member_function_pointer_impl : bool_ {};

template
struct is_member_function_pointer_impl
  : is_function {};

template
struct is_member_function_pointer 
  : is_member_function_pointer_impl {};
