This specific problem can be addressed at least partially by setting reasonable defaults for new arguments. This is a necessary technique when the publisher of a language or a module/package wants to extend the functionality of a function or method without introducing a new name for the function/method. The general problem is usually addressed in dynamic languages by running a test suite. -- http://mail.python.org/mailman/listinfo/python-list
