In test_operator we find the following lines:

        class C(object):
            def __getattr(self, name):
                raise SyntaxError
        self.failUnlessRaises(AttributeError,
operator.attrgetter('foo'), C())

Obviously "__getattr" has no effect. However, when changing it to
"__getattr__", the test fails. Is there is any motivation for this test
in the first place? If yes, why the typo and why the error when the typo
is corrected?
