MPL in general gives no guarantee about the exact types that operations produce.

Please don't treat me like a customer of a US cellphone company (grin). template<long I> struct long_ { static const long value = I; template<long J> struct create { typedef long_<J> type; }; }; template struct plus { typedef typename T0::template create::type type; };
