Should the Standard allow declarations of variadic templates or member functions of class templates where only an empty expansion would be well-formed? For example,

    template<typename ... T> struct A {
      void operator++(int, T... t);
    };
    template<typename ... T> union X: T... { };
    template<typename ... T> struct A: T..., T... { };
