I think you struck at the heart of the matter earlier when you noted that this is the simplest way to declare a static variable in python. Using the 'global' keyword is the other way, and is much more explicit, and much more widely used. I also see this as the main use of the 'notlocal' keyword to be introduced in py3k (it also fixes the example given by Istvan above). If the main value of this behavior is to declare a static variable, it seems like an argument to create a more explicit syntax for static variables. In the example above, the function only needed a static integer, but created a one-length list instead because this quirk doesn't work for immutable values. -- http://mail.python.org/mailman/listinfo/python-list
