hey, did u read my reply fully? i too feel that this matter of raising unbound local error in one case and not raising it in the other must be analysed...
quoting from the documentation "If a name binding operation occurs anywhere within a code block, all uses of the name within the block are treated as references to the current block. This can lead to errors when a name is used within a block before it is bound. This rule is subtle. Python lacks declarations and allows name binding operations to occur anywhere within a code block. The local variables of a code block can be determined by scanning the entire text of the block for name binding operations." -- http://mail.python.org/mailman/listinfo/python-list
