[Python-Dev] PyDict_Get/SetItem and dict subclasses

PyDict_GetItem() and PyDict_SetItem() don't call __getitem__ and __setitem__ 
for dict subclasses. Is there a reason for that?

I found this surprising behaviour when I replaced a dict by a custom dict 
checking the key type on set. But my __setitem__ was not called because the 
function using the dict was implemented in C (and I didn't know that ;-)).
