Is this high-performance enough? Might be worth thinking that through.

I've never actually seen any website ever call this function, so I think sharing code and guaranteeing that all the necessary work in remove() runs is probably more valuable than squeezing more performance out of this function.

I guess I can at least iterate backwards, though.
