Not working, unless f has been called at least once. But what I didn't know
(and always wondered) if the classdefinition inside a function can use the
outer scope - and apparently, it can! Cool.
def f(baseclass):
class C(baseclass):
def __init__(self):
self.a = 'a'
f.C = C
def foo(self):
print baseclass
return C()
c = f(object)
print f.C
c.foo()
