    template<class T> struct hash<shared_ptr<T>>;
    		 (dal C++11)
    Il modello di specializzazione di std::hash per std::shared_ptr<T> consente agli utenti di ottenere gli hash di oggetti di tipo std::shared_ptr<T>.
    Original:
    The template specialization of std::hash for std::shared_ptr<T> allows users to obtain hashes of objects of type std::shared_ptr<T>.

    Per un dato std::shared_ptr<T> p, questa specializzazione assicura che std::hash<std::shared_ptr<T>>()(p) == std::hash<T*>()(p.get()).
    Original:
    For a given std::shared_ptr<T> p, this specialization ensures that std::hash<std::shared_ptr<T>>()(p) == std::hash<T*>()(p.get()).
