Now the compiler gives an error on the same code

fail.cpp: In substitution of ‘template<class T, class ... Ts> using Tail =
List<Ts ...> [with T = Ts ...; Ts = {Ts ...}]’:
fail.cpp:6:23:   required from here
fail.cpp:4:23: error: template argument 1 is invalid
 using Tail=List<Ts...>;
                       ^
fail.cpp:7:9: error: expected type-specifier before ‘Tail2’
 using A=Tail2<int, char, char>;
