Revision 7889107be7cb5a28aabcdfa33778bdce3e9b5c27 authored by Jeremy Hylton on 01 March 2001, 06:09:34 UTC, committed by Jeremy Hylton on 01 March 2001, 06:09:34 UTC 
Fix core dump in example from Samuele Pedroni:
 
from __future__ import nested_scopes
x=7
def f():
    x=1
    def g():
        global x
        def i():
            def h():
                return x
            return h()
        return i()
    return g()

print f()
print x

This kind of code didn't work correctly because x was treated as free
in i, leading to an attempt to load x in g to make a closure for i.

Solution is to make global decl apply to nested scopes unless their is
an assignment.  Thus, x in h is global.
