Well, I had problems at that time posting at all, so finally it escaped
without a changed subject ;-)

Great idea!

Dont' know, but it can be modified (although this is dangerous):

>>> def f(): pass
...
>>> f.func_globals
{'__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__',
'__doc__': None, 'f': <function f at 0x00767F08>}
>>> f.func_globals.clear()
>>> f
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
NameError: name 'f' is not defined
>>>

I intend to update this stuff stealing from your ideas, but probably
python-dev is not the correct place to discuss this (IMO).
Should I post it again (with a better subject) to python-list,
and we continue there?
