at the line marked with #:
//-------------------------
template<class T>
struct add_rval_ref {
typedef T&& type;
};
template<>
struct add_rval_ref<void> {
typedef void type;
};
template<class T>
typename add_rval_ref<T>::type create();
template<class T, class Arg>
decltype(T{create<Arg>()}, char()) f(int);
template<class, class>
char (&f(...))[2];
static_assert(sizeof(f<int, void>(0)) != 1, "Error"); // #
