 The correct OO way to do this would be to have a superclass Topping and 
a subclass oPepperoni. You would then do something like new 
Pepperoni("cripsy and spicy"). You could have a classVar that had the 
topping name.

  What language do you use that computes charactersitics of the object 
being created basd on the name of the variable you store it in?

 If I do something like:

  $meat_topping = $pepperoni;
  unset($pepperoni);

 What should the "name" be then?

 Mike.
