URNG concept
 
template < class T, class U >
concept bool Same = std::is_same<T, U>::value; // see below
(ranges TS)

The concept Same<T, U> is satisfied if and only if T and U denote the same type.

Despite being specified using it, there need not be any subsumption relationship between Same<T, U> and std::is_same<T, U>::value.

For the purposes of constraint checking, Same<T, U> implies Same<U, T>.

Notes

The additional requirement on constraint checking differentiates Same from std::is_same.
