I love it. It helps remove a lot of methods in base classes like Object 
and Morph that don't really belong there.

Please note that in Cuis, #is: does not call #isKindOf:. All 
implementors are explicit. This also means that you can see the 
protocols an object conforms by reading the inheritance of the #is: method.
