In both Python 2.x and 3 (a few months old build of Py3k though), the
traceback isn't the same. For Python 2.0 you could write it like:
def handle_exception():
...
raise sys.exc_info()[0], sys.exc_info()[1], sys.exc_info()[2]
Its not clear how that would be spelt in py3k though (and from what I can
see, sys.exc_info() itself has an uncertain future in py3k).
