// This is to test the notion of "index" used in in
// hlt.language.util.SetOf (method "indexof(Object)".  Is it the order
// in which the "Indexed" object is created that gives it its index?
// Then, this is also the index in the AbstractList "base" that contains
// all possible elements, each at its index.

// public final int indexOf (Object object)
// {
//   if (object instanceof Indexed)    // WARNING: this works only if
//     return ((Indexed)object).index; // index is the position in base 
//
//   return base.indexOf(object);
// }

// In the object is not an Indexed instance, the base index is returned.
