where Range<N> contains sequence 0,...N-1 and is defined here. Now you can use it like this:

It turns out pack is quite tricky to make non-recursive, but as promised, here is a non-recursive, constexpr version of unpack (complete, live example):

It turns out pack is quite tricky to make non-recursiveandconstexpr, but as promised, here is a non-recursive, constexpr version of unpack (complete, live example):

int val = pack<int>(1, 0, 1);
// 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 1
std::cout << unpack(val) << std::endl;
// 0 0 0 0 0 1 0 1
std::cout << unpack<8>(val) << std::endl;

int val = pack<int>(1, 0, 1);
