Not quite. You are creating a new class with the desired property, but it can sometimes be desirable to assert properties about types that already exist. For example, suppose I invent a GroupUnderPlus property for types for which the + operator has group properties. I would like to be able to say that int has that property, and not have to derive a new class from int in order to do so. -- Andrew Koenig, ark@research.att.com, http://www.research.att.com/info/ark
