    template< class T >
struct hash<std::shared_ptr<T>>;
    		(since C++11)

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

    For a given std::shared_ptr<T> p, this specialization ensures that std::hash<std::shared_ptr<T>>()(p) == std::hash<decltype(p.get())>()(p.get()).
