I need to do initialize some properties of new instances of a DataSkin

object hasn't been stored at that point.
Doing self.__dict__['name'] = 'Rincewind' seems kinda ugly. Maybe newItem
should by default call a function
(ZPatterns 0.4a5, Zope 2.2.0) If an agent raises an exception, you don't get
to see the traceback. Instead, the object is simply not added (if the
exception was in _objectAdded, donno what happens in _objectChanged). This
makes debugging agents basically impossible...
