# std::experimental::ranges::Same

From cppreference.com
< cpp‎ | experimental‎ | ranges

Defined in header `<experimental/ranges/concepts>` |  |
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.
