I'll leave it to someone else to rule on that, they make my head hurt ;)

I will note that this works:

      using type2 = list<int(Ts)...>;

and this works:

      using type4 = list<int(*)(Ts)...>;

And of course all these work:

      template<class X>                                                         
        using F = int(X);                                                       
      using type1 = void(F<Ts>...);                                             
      using type2 = list<F<Ts>...>;                                            
      template<class X>                                                         
        using Fp = int(*)(X);                                                   
      using type3 = void(Fp<Ts>...);                                           
      using type4 = list<Fp<Ts>...>;
