[Python-Dev] Why does __getitem__ slot of builtin call sequence methods first?

The new ndarray object of scipy core (successor to Numeric Python) is a
C extension type that has a getitem defined in both the as_mapping and
the as_sequence structure.
The as_sequence mapping is just so PySequence_GetItem will work correctly.
As exposed to Python the ndarray object as a .__getitem__ wrapper method.
Why does this wrapper call the sequence getitem instead of the mapping
Is there anyway to get at a mapping-style __getitem__ method from Python?
This looks like a bug to me (which is why I'm posting here...)
Thanks for any help or insight.
