It seems to me that what you are describing is exactly what abcs were added for in 2.6, in particular registration: class AnotherClass(metaclass=ABCMeta): pass AnotherClass.register(basestring) assert isinstance(str, AnotherClass) Please read this first: http://www.python.org/dev/peps/pep-3119/ and tell us why that would not work.
You're right, that is exactly the need I was looking to fill. Thanks for pointing it out!
Now I have only two regrets: first, that our shop is still using 2.5 and this functionality is new in 2.6; and second, that it does not appear to include an easy way to check the types of elements of a sequence or mapping.
Still, I can see that this is a very carefully considered PEP and is the best solution for the future, so I will study it carefully and incorporate it into our practices ASAP.
