Walter and Andrei have been discussing putting together a DIP with a
"ProtoObject" which will be the new root class below Object where
ProtoObject itself has only the bare minimum required to work as a class
(not monitor object, no toString, no opEquals, etc.). Classes could then
derive from ProtoObject directly instead of from Object, and then they could
define any of the functions that are currently on Object with whatever
attributes they wanted (or not define them at all). The DIP has not yet been
written, and the details still need to be ironed out, but that's the gist of
the direction that's currently being considered.
