JavaScript Iterator Class

Question

Do you know a JavaScript library that implements a generic Iterator class for collections (be it Arrays or some abstract Enumerable) with a full set of features, like the Go

Answer 1

Ok, the enumerable pattern is not a real iterator then.

Is this (below) useful for you? It conforms to the sematics you gave at least. As usual there are tradeoffs to be made here and there, and I didn't think very hard when deciding this time :).
And maybe you would like to be able to send in a number or two and iterate over a range in that way. But this could maybe be a start (there's support for iterating over hashes, arrays and strings).

It's a whole demo page which runs itself and does some debug output, but the (possibly) interesting stuff is in the

window.npup = (function() {
    [...]
})();

spot.

Maybe it is just me who doesn't get it at all, but what would you use such a java-like Iterator for in a real situation?
