PyDict_GetItem() and PyDict_SetItem() don't call __getitem__ and __setitem__ for dict subclasses. Is there a reason for that?
http://bugs.python.org/issue10977 “Currently, the concrete object C API bypasses any methods defined on subclasses of builtin types.”
I think that's the correct behaviour. If you expect to get an arbitrary mapping, just use the abstract API. You should use PyDict_GetItem when you know the object is exactly a dict (generally because you have created it yourself, or you know at least where and how it was created).
