[Zope-dev] Is this a ZClass/Propertysheet bug?

See http://www.zope.org/Members/paulabrams/howto_deleteundeadzclassprops
for help.

It is not a bug per se, Python (upon which ZOPE is based) is built this
way, i.e. if you create a class with certain attributes, every instance
will keep those attributes, even if they are deleted from the class
itself, and new instances that are instansiated from the now modified
class will not.
