Re: [Python-Dev] Extending types in C - help needed

...

Yes, alas. The type you would have to declare is 'etype', a private type in typeobject.c.

Does this mean this is the wrong route, or is it absolute impossible to create a subtype of PyType_Type in C with additional slots?

I wish I had time to explain this, but I don't. For now, you'll have to read how types are initialized in typeobject.c -- maybe there's a way, maybe there isn't.

Any tips about the route to take?
