template<class T, T N>
using make_integer_sequence = integer_sequence<T, see below>;
If N is negative the program is ill-formed. The alias template make_integer_sequence denotes a specialization of integer_sequence with N template non-type arguments. The type make_integer_sequence<T, N> denotes the type integer_sequence<T, 0, 1, ..., N-1>. [ Note: make_integer_sequence<int, 0> denotes the type integer_sequence<int> — end note ]
