Ayup. I am extremely far from an expert here, but anyone wanting to have an informed opinion should really re-read the threads after these posts: http://mail.python.org/pipermail/python-dev/2006-September/068569.html http://mail.python.org/pipermail/python-dev/2007-January/070772.html I would recommend requesting review from either Nick Maclaren or Tim Peters as well. -- Aahz ([EMAIL PROTECTED]) <*> http://www.pythoncraft.com/ "Typing is cheap.
