Shouldn't the user think the same with "head" or "front"?

I think the problem is "next" in this case: it should be "moveToNext" or 
something that shows that you are changing the input, not just 
requesting the next element in the range.

But keep "next". Once the user starts using ranges, he'll understand the 
terminology, which is pretty straightforward.

I vote for first/last.
