Description
LEWG voted that (begin, end) pairs don't need a special name; tuple-like is fine.
LEWG observed that syntax for compile-time constants was not ergonomic. Some suggested index_sequence<begin, end> (generalizing to index_sequence<IndexType, begin, end>). Some suggested convenience aliases, such as the following for a pair of compile-time int.
template<size_t X, size_t Y>
inline constexpr pair<integral_constant<int, X>, integral_constant<int, Y>> md_rng;
