Yes, and that's indeed a potentially good reason to remove opCmp and 
opEquals from Object, and one I'd thought of myself but hadn't got round 
to bringing into the conversation.

The need to cast from Object to some class just to compare objects of 
that class will go away, but you might still have similar casts it if 
you have a class with a comparator and you create subclasses of it.
