I avoid using that at all ever, since it is so brittle. Usually when you're doing this sort of thing you're writing code that is going to break later when you or somebody else tries to change it -- so make sure you put in some clear comments! You can use a single underscore to indicate "private-ish, but not so private", e.g., change self.__order to self._order and then there will be no name mangling. But users still no they aren't supposed to muck with order.
