As you found out: no, this isn't supported. To work around, you can wrap the extension module with Python module which invokes an explicit module initialization function; you then need to lookup the subclasses dynamically (going through thread_state->interp->modules). > As to question 2, I'm in the process of prototyping that approach to see if > it > is feasible in our code and if so, (and people find it useful) I'll attempt > to write a PEP for that feature. I'd like to see the module initialization/finalization be redone for Python 3, in particular with explicit finalization procedures. If Python 3 still supports multiple interpreters, this aspect should be taken into account. Whether there is any chance to add the PEP to 2.x, I don't know - it needs to be written first.
