And $self2, $self3, ... to the object methods of nested classes and
$cls2, $cls3, ... to the classmethods of those classes...?

And when we are at it, here is a nice little exercise for the
proponents of compiler magic.

Write a decorator that takes and returns a method and prints the
object the method is bound to. It's very easy to do it when the object
is passed explicitely:

def print_self(func):
    def call(self, *args, **kwd):
        print self
        return func(self, *args, **kwd)
    return call

Conceptual clarity isn't always an entirely bad thing to have.
