Good point. Usually I don't use it at all, but I seem to remember that I
wanted to enforce the C++ behaviour referred to in the Reference Guide:

If you want to use a different set of translations in the subclass, you'll
get the behaviour you want by just calling self.tr() without creating any
helper methods. You won't inherit any translations, though, or will you?
