Compile-time integer sequences C++14

Show all headers | View raw

hello,

20.5.1 of the C++14 draft reads

example:
template<class F, class Tuple, std::size_t... I>
decltype(auto) apply_impl(F&& f, Tuple&& t, index_sequence<I...>) {
return std::forward<F>(f)(std::get<I>(std::forward<Tuple>(t))...);
}

What I do not understand:
The I in get<I> is declared as parameter pack in the template
parameter list, but should be a number or a type of one of the tuple
elements. Am I wrong?

How f could be declared (see the ellipsis in the call)?

Best regards
Piet
