Well, I've never been really into the guts of Python ... but could you shed
some light for me on that why these two things are different?
What I experienced was this "feature" broke my code (actually it was in a
3rd party code library) and it took a while for me to recognize the
documentation was wrong
(or whatever, depending on your explanation..) and slice objects shouldn't
be passed to __getitem__ that way in Python 2.2
(and that this works for Python 2.3)

Well, then my patches will stay and slow down things a bit.
