[comp.sys.next] Using a List for an ordered set

jacob@gore.com (Jacob Gore) (10/14/89)

The documentation for class List says:

  List allows easy manipulation of collections of objects. Collections can be
  manipulated as fixed or variable sized lists, sets, or ordered collections.

Is the author just being philosophical here, or is there really some way to
make a List behave as an ordered collection or a set (or both)?

In methods that "find object in the list", what is used to determine
equality of objects -- the -isEqual: method of one of the two objects (if
so, which one's?), or just comparison of their id's?

Is there a plan to reproduce more of Stepstone's Foundation Library, or
make a library of similar functionality?

Needing an ordered set or at least an ordered collection,
Jacob
