Liskov substitutibility would seem to suggest deriving int from bool, not the other way around. That is: If I have a program that uses bool values, I can change it so that it uses int values without affecting the behavior of the program. The reverse is not true. I wonder if this is the circle-ellipse problem over again? -- Andrew Koenig, ark@research.att.com, http://www.research.att.com/info/ark
