[Zope-dev] Hotfixes and __bases__

[Dyon Balding]

In Caseman's How-To named "Extend Zope Dynamically with Hotfixes", at
http://www.zope.org/Members/Caseman/Dynamic_Hotfix, he mentions that you
could: "Add new base classes to existing classes".

I have tried this, and can't get it to work, my question is: is it
possible?, and if so, how do I make it work? :)

I am using Python 1.5.2, which supports dynamically updating the
__bases__ attribute.   I can successfully update the bases in simple
Python classes, but when I try to do it to a Zope (2.3.2) class
(specifically Folder), my assignment to the __bases__ attribute doesn't
update it.

Is what I'm doing even possible?

thanks
