Something that I've always considered missing from containers ([linked] lists particularly) was the ability to give .next() a number of steps to take. In other words, provide list.next(3) which would be the same as list.next.next.next. If it hits a null, it should just return null, rather than throw an exception. (Maybe I expected a null.)

I assume that you're talking about container iterators...

You'd essentially like to be able to skip elements. iter.next(3) sounds like it returns a container with the next three elements in it. iter.skip(2).next or iter.advance(3) is what you want?

The .advance(3) form looks good... I see what you mean about .next(n) reading like a slice -- although that could be a neat trick too.
