Anyway, I also tried to imply that it matters if the number of list items would ever be huge. It seems that is indeed possible (even if not likely) so I think iterators are useful.

But according to Nick's post, there's some sort of uniquification that is done, and the algorithm currently used computes the whole list anyway.

I suppose that one could do the uniquification lazily, or find some other way to avoid that computation. Is it worth it to optimize an unlikely case?
