Not quite. I am aware of various iterator implementations, including yours.
What I wanted is an example of implementation Michael suggested,
because he said that his variant is better then mine, so a wanted to
look at it to compare.

Do I understand correctly that you are speaking about this article:
http://opensoft.homeip.net/articles/iterator_pattern.pdf ?
As far as I understand, since iterators described in the article do
not have the concept of a current item,
they also do not have concept of an index, and hence are not relevant
in the context of this discussion.
