[New-bugs-announce] [issue9226] erroneous behavior when creating classes inside a closure

New submission from Chris Monsanto <chris at monsan.to>:
I have a function whose closure contains a local variable that shadows a global variable (lets call it x). If I create a class as follows:
class Test(object): x = x
Test.x will contain the value of the global x, not the local x. This ONLY happens when the names are the same, and it only happens in the class body; i.e., "class Test(object): y = x" and class "Test(object): pass; Test.x = x" work fine.
However, if there is an assignment x = x AND you make other assignments, such as y = x, in the body, the other variables will have the wrong value too.
Test case attached. Problem noticed on Python 2.6.2 on Windows and 2.6.5 on Linux.
