The instance-of hierarcy is differenct and separate from the inherits-from hierarchy. The fact that we tend to use "is-a" for both makes it confusing. Try this. Draw a diagram of the major players (Object, Class, etc.). Mark all the instance-of relationships with one color, and the inherits-from relationships with another color. Study the diagram real hard. Study it real hard. When you are done, you probably won't understand it any better, but you will have a cool diagram to hang on your wall. :-) -- -- Jim Weirich jweirich@one.net http://w3.one.net/~jweirich --------------------------------------------------------------------- "Beware of bugs in the above code; I have only proved it correct, not tried it." -- Donald Knuth (in a memo to Peter van Emde Boas)
