Python Reference Manual 3.3. The wording is not the best. Should file a doc bug.

"For instance, if a class defines a method named __getitem__(), and x
is an instance of this class, then x[i] is equivalent to
x.__getitem__(i)."

In this case, although x.__getitem__ exists, x is an instance of a
class which *does not* define a method named __getitem__(), so it
should not be called.
