I understand that you can use __getitem__ as a hook to
modify indexing behavoir in a class. That's why
__getitem__ not only affects  but also for loops,
map calls, list comprehension, etc. For loops, etc.
work by indexing a sequences from zero to a higher
index until out-of-bounds is reached. But why does
>>> class stepper:
... def __getitem__(self, i):
... return self.data[i]
>>> 'p' in X
What does 'in' have to do with indexing?
