[Zope-dev] ZClass.py?

I'm slowly updating the whole ZQR and came across this: cb_isMovable=cb_isCopyable in ZClass.py Does this need to be there or changed to cb_isMoveable, like the one in CopySupport.py? Also can someone who knows about the objectIds_d, objectItems_d, objectMap_d in ObjectManager.py, mention the purpose of having them there and if I should mention them in the ZQR? they seem to be left over from something, can't find any other references to them. David, empty space...
