std::experimental::ranges:: Same

From cppreference.com
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 .
