- can use 'XX.empty()' instead of 'XX.size() == 0', 'XX.size() < 1' or 'XX.size() <= 0' or for simpler coding. It also has the same number of characters as '!XX.size()' and /might/ be more readable - many size checking had 'XX.size() > 0', 'XX.size() != 0', or 'XX.size() >= 1' when a simple 'XX.size()' suffices
