std:: hash (std::experimental::propagate_const)

The template specialization of std::hash for std:: experimental :: propagate_const < T > allows users to obtain hashes of objects of type std:: experimental :: propagate_const < T > .

For a given std:: experimental :: propagate_const < T > p , this specialization ensures that std:: hash < std:: experimental :: propagate_const < T >> ( ) ( p ) == std:: hash < T > ( ) ( p. t_ ) , where p. t_ is the pointer-like object wrapped by p .
