Summary: nested scopes segfaults
Initial Comment:
In current CVS:
If a function was compiled with nested scopes
and with a name resolved in an outer scope, it
expects a cell object in the func_closure slot when
executed.
However the user can legally del f.func_closure.
Core dump follows next time the function is called.

Here is the testcase: (import this as a module
e.g. test_scopes.py, since I'm not sure that from __future__
etc. works interactively yet.)
#test_scopes.py
from __future__ import nested_scopes
def make_closure():
x=1
def f():
print 'x =', x
return f
f=make_closure()
print f.func_closure
f()
del f.func_closure
print f.func_closure
f()
