template < class T > struct hash< std::experimental::propagate_const <T>> ;
(library fundamentals TS v2)

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> , 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
