Yes, Sam's selector will definitely stop climbing the DOM once it

Actually, I don't think that's true. I believe :first, :last, :eq,
etc apply their logic after the list of potential elements has been
built. The results are accurate of course, but I don't see where
their is any optimizations for the :first or :eq cases to short-
circuit the climb.

Ah, I see what you mean. I misunderstood what was actually meant by
"stop climbing the DOM" and assumed he meant stop returning elements.
Anyway, you're right. It won't return any of the other elements, but
it *will* climb all the way up before it returns just the first match.
Thanks for the clarification, Mike!
