Heh, yeah. My intention is to ignore that altogether. The general policy in Python is "if ever it MIGHT be assigned to, it belongs to that scope" (so even "if 0: x = 1" will mark x as local), so sticking to that would mean treating x as local regardless of the try/except. (On an unrelated subject, I'm keeping the "sublocal scope" concept from the original PEP on ice. It might be worth implementing exception name binding with a sublocal name. But that's for a completely separate PEP.)
