Bill, you have implemented 'retract' and friends, but there is no 'RetractableTo(NonZeroInteger)'. Since the interpreter does not seem to find 'retract', my question to the people who know the interpreter is, when will the interpreter *automatically* apply 'retract'? What is it actually the interpreter looks up. Does it look for the 'CoercibleTo' category or simply for the existance of an appropriate 'coerce' function? As far as I remember, the interpreter never applies 'convert' or 'retract' automatically. But how does it find out about a possible coercion?
