I've ported zope.hookable too, but I don't need it until it's time to port zope.component (and I think the same goes for zope,security which I think is next if I remember correctly), so I'm not merging the branch yet. It's full if ugly Python 3 hacks, as it's a c-extension. Feel free to take a look and complain if you you like. :-) http://svn.zope.org/zope.hookable/branches/regebro-python3/ -- Lennart Regebro, Colliberty: http://www.colliberty.com/ Python, Zope, Plone blog: http://regebro.wordpress.com/ Telephone: +33 661 58 14 64
