Ah. I *knew* I was missing something obvious.

I think it should either (1) always use walk_silly, i.e. the name
associated with the function object, or (2) the attribute name used to
access a method should be stored in the method object so that the
implementation of super can access it.

I'd probably prefer (1). (2) is too much DWIM for my tastes.

Yes. super should evaluate to an unbound method object.
