The Standard is not clear on the treatment of an example like the following, and there is implementation variance:
template<class ...Types> struct Tuple_ { // _VARIADIC_TEMPLATE
template<Types ...T, int> int f() {
return sizeof...(Types);
}
};
int main() {
Tuple_<char,int> a;
int b = a.f<1, 2, 3>();
}
Rationale (February, 2019):
This issue is covered in more detail in issue 2395.
