Yes, exactly! I knew it was in there somewhere, but I couldn't find
the ref.

The function you pass to each has a second optional index param:
$$('.foo').each(function(elem, index) {
elem.update('I am element ' + index);
});
It's not all that clear in the docs but it's mentioned for the
iterator param here:
http://api.prototypejs.org/language/Enumerable/prototype/each/
Is that wat you were looking for?

I have an extended array, result of $$('.foo'). Given a single member
of that array as an object, how do I find the next element in that
array, or the first if the next would wrap?
I could swear there used to be an operator that worked over an
enumerable and maintained an index element as you went, so you could
reference by position within the enumerable, but I can't find it by
hunting in the documentation. Can anyone help me out?
Thanks,
