Sorry, but I'm really puzzled at this point. What do you know about *my* system? You seem to be of the kind of people who classify everything (no attack intended: just an observation). In my experience, about half of the people (but only half) think this way: if it has a weight, it must belong to the class of massive things. The rest of the world (to whom I belong) view things as having properties without the need of classifying. Maybe it is a matter of being left- or right-brained... > Weight is a number with all properties of real values + ones of mass, > acceleration etc. But Spike's weight (tm) is not a number. It is another > singleton specific to Spike and unrelated to anything else = nothing. Spike's weight is a physical property, but its abstraction (i.e. what I need from weight in my application) is its value in measurement unit. BTW, I would not say it is a singleton. Weight is not an object at all, it is a simple value. Remember: not everything is an object (I hope Michel Gauthier reads this) -- --------------------------------------------------------- J-P.
