What you'd do next is to initialise your types in the module (or let CPython do it for you through the inittab)

I'm not sure I completely understand it. I assume that executing these two lines, in context of the module:

const char* c = "class A(object):\n\tpass"; PyRun_StringFlags(c, Py_file_input, d, d, NULL);

creates complete and initialised A class within this module. Doesn't it?

Yes, it does. What I meant what: if you want to let the dynamically generated Python classes inherit from your extension types, then initialise the extension types before hand so that they turn up in the module dict and your Python code can use them normally as base types.
