Easy, it does not use the C++17 deduction rules at all, it is explict.
That is:
std::make_tuple is defined as:
template<typename ...T>
auto make_tuple(const T &...a)
{
return std::tuple<T...>(a...);
}
And there is no C++17 class deduction rules going on, it is pure normal C++11
template function deduction rules.
