[Zope] Persistence triggering

When appending to a list in Zope In a persistent class I cannot just do: self.list.append(item) As it will not trigger the persistence mechanism. I can treat it like an imutable, but that is rather tedious: _list = self.list _list.append(item) self.list = _list But can I also do? self.list = self.list + [item] Regards Max M Max M. W.
