--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
No, because not all enumeration types behave like the integers:

enum E : unsigned char { };

namespace std {
  template<> struct equal_to<E> {
    bool operator()(E l, E r) const noexcept {
      return ((unsigned)l % 16) == ((unsigned)r % 16);
    }
  };
}
