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.
