I'm currently implementing a parser to handle Python 3.0, and one of the points I found conflicting with the grammar specification is the PEP 3104.
It says that a shortcut would be added to Python 3.0 so that "nonlocal x = 0" can be written. However, the latest grammar specification (http://docs.python.org/dev/3.0/reference/grammar.html?highlight=full%20gramm...) doesn't seem to take that into account... So, can someone enlighten me on what should be the correct treatment for that on a grammar that wants to support Python 3.0?
