Nope. Because then a lot of people would write something like this:


class Foo(object):


   def bar(self):
       bar() # note the missing self.


And this would lead to errors because self was missing from the call
to "bar".

And you'd need a disambiguation for methodname/global-name-clashes. The
global-statement would work, but then code could break when all  of a
sudden a subclass defines a method that hitherto was only known as global.
So via subclassing, you introduce *arbitray* and hard to debug errors.

No. I'm certain, not a good idea.
