Another thing about monkeypatching is that it seems like the best way to write an extension class where you want half to be in C/C++ and half in Python. I'm in the middle of working on such a class and there are plenty of members that just don't need to be in C++.

Is there a better/preferred idiom for such a thing? I don't want to subclass my new class because I want any objects created on the C++ side to also get the python methods.

Have you tried this? I believe it doesn't even work; types defined in C++ are supposed to be immutable. Try adding a new method to list or dict.

However the C++ side should be able to create instances of the Python-defined subclass as long as it runs in a method, since it has a reference to the actual class.
