+Perhaps we should always just include its address. Clearly two otherwise
+identical protected objects are still fundamentally distinct, since they
+each have their own specific lock. That is all I was trying to accomplish
+with the protected ID.

+OK, I guess, but isn't that fundamentally true of any limited type? You've
+often made the point that the object identity of a limited object is an
+important part of its abstraction. I was just wondering why protected
+objects ought to be special in this way.
