Hmm, I’m not sure I agree there. There’s a difference between using C++ because I just want to avoid obvious waste (interpreter, GC pauses…), and actually optimizing my code. I would put v.empty() vs v.size()==0 in the latter category. Day to day, I mostly trust that std::vector is not wasting cycles except on resizes.
