Defined in header
<experimental/ranges/concepts>
template< class T, class U >
concept bool Same = std::is_same <T, U>::value; // see below
(ranges TS)
concept bool Same = std::is_same <T, U>::value; // see below
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>.
[edit] Notes
The additional requirement on constraint checking differentiates Same from std::is_same .
