List:

I need to provide an enumerator for something that doesn't have an
underlying collection.

Aside from providing function -4, what other functions do I need to
supply to provide this functionality.

I'm thinking of things like providing all different traversals for a
tree, traversing a linked list . . those sorts of things.

What I need is a discussion of the required functions, their IDs, and
what they should return.  I've seen examples that Just Work, but I'm
having trouble making sense of what requirements are being implements.

Thanx
