La versione di questa funzione nel non specializzato modello std::pointer_traits chiama semplicemente Ptr::pointer_to(r), e se Ptr non fornisce una funzione di membro static pointer_to, istanze di questa funzione è un errore di compilazione.
Original:
The version of this function in the non-specialized std::pointer_traits template simply calls Ptr::pointer_to(r), and if Ptr does not provide a static member function pointer_to, instantiation of this function is a compile-time error.
