Some language proposals.

Paul,

Your outputs were all incorrect.

 >>> a = 5
 >>> def b():
...     a = 6
...     print a
...
 >>> b()
6
 >>> print a
5

What you give doesn't work, here's a slight modification:

 >>> a = 5
 >>> def b():
...     a = 6
...     def c():
...         a = 7
...         print a
...     print a
...     return c
...
 >>>
 >>> b()()
6
7
 >>> print a
5


I don't know what you were trying to prove, but next time, test it out.
