Because detection assignment to a name in the first AST scan and then using LOAD_FAST and STORE_FAST for access to and assigning to that name is a simple, easy thing to implement, while doing execution analysis to detect that it can't possibly be set before being referenced is really hard. -- http://mail.python.org/mailman/listinfo/python-list
