Aah, you're right. Well, we could perhaps hack ObjectManager to store its
kids in a dictionary, but I'm not sure whether that'd break Acquisition.
Does anyone know whether Acquisition works in a way which is compatible with
__getattr__?
[I guess I could try it, but I'm kinda Zoped out today after fighting Z2
conflicts again.]
