I am trying to let a user of my library inherit a Python class, and override some of its behavior. Simply declaring a class with the same set of methods, and calling ToPython on it somewhat works thanks to Python's duck typing.

Problem is that approach fails to pass isinstance and obj is Class tests in the 3rd-party Python code.

If there's no existing way to deal with it, I'd be happy to implement the necessary machinery, if somebody would give some directions on where to start.
