And you shouldn't _expect_ everything to break, particularly with minor-
version upgrades, but you should expect that things _can_ break. It really
isn't something that you can "not find" - it's a basic tenet of Python that
backward compatibility is not guaranteed. More to the point, it is to be
actively avoided if it introduces too much complexity.
