What I suggest doing is submitting a doc patch to http://bugs.python.org/ explaining the ``done`` attribute with a note that you're not sure whether the attribute is intended to be undocumented. Alternatively, you might look in the svn logs to find out who added the ``done`` attribute and if they're still active in the Python community, ask them directly. -- Aahz ([EMAIL PROTECTED]) <*> http://www.pythoncraft.com/ The best way to get information on Usenet is not to ask a question, but to post the wrong information. -- http://mail.python.org/mailman/listinfo/python-list
