Me wasting time with writing some itertools esque functionality in C++ 20's ranges style.
Stuff like:
for (auto&& [i, n] : PyRanges::range(3, 5) | PyRanges::enumerate) {
std::cout << '[' << i << ", " << n << "]\n";
}
/*[0, 3][1, 4]*/Edit: I just found out this is basically just a worst version of cppitertools.
