I expect you'll get the same response, especially given potential (though slight) chance for backward-compatibility issues.  What I find curious is Guido's reference to "the rule that class bodies don't play the nested
scopes game" (and his subsequent explanation).  Is there something about that in the language reference?  If so, the patch should be updated to link to that section.  If not then it should be added to the language reference.

That said, it wouldn't hurt to ask on python-dev, particularly in light of that new opcode.
