Er, oops, I used "ordered" to mean two things here. I meant that the code regarding aliases would use an _unsorted_ list (where we care about keeping the original insertion order). But what I think is harmful is a _sorted_ list, because of the "accidentally quadratic" nature, and because it's easy to call its functions on an unsorted list. -Peff
