variable refences for nested functions

[thephoenix235 at gmx.net]

A class would be too heavy duty. You're idea works great. I'm doing this
now.

class Blank: pass


def foo ():
   top = Blank ()
   top.a = 1

   def bar():
      print top.a
      top.a=2  

   bar()
   print top.a

foo()


Thanks.
