New-style classes and special methods

[Jp Calderone]

  Consider this class:

    class Foo:
        def __getattr__(self, name):
            return lambda arg: arg

  It can be used thusly:

    f = Foo()
    print f[10]

  Producing the output "10".  Now consider this class:

    class NewFoo(object):
        def __getattr__(self, name):
            return lambda arg: arg

  When used in the same way, this exception is raised:

    TypeError: unindexable object

  From a quick glance at the source, it seems that neither tp_as_mapping nor
tp_as_sequence are being initialized, presumably because __getitem__ isn't
seen as being defined.

  Is this analysis of the behavior correct?  If so, what are the chances of
this being "fixed"?
