Content
I haven't fully thought this one through, but perhaps we could: - deprecate calling the current concrete APIs with subclasses (since doing so may break subclass invariants) - add "PyBaseDict_*" APIs (etc) that subclass implementations can call. - offer a compatibility header for earlier versions that #defines the new APIs back to the old ones This would be 3.5 PEP territory, though.
