FWIW, something like this:
template<class T>
struct promoted
{
  typedef BOOST_TYPEOF_TPL(T()+T()) type;
};
Unary plus is slightly shorter then binary plus: BOOST_TYPEOF_TPL(+T())
:)

Would work on any integral type without registration.
Enums can't be the result of a promotion, so no need to worry about

My code is very lightweight typeof simulation with only four types:
1 - int
2 - unsigned int
3 - long
4 - unsigned long
One thing I can say for sure -- this will be much easier to port :)
