It's a little inconsistent with removeAt, but I guess it can't be avoided
without overloading.

If we had slice-assignment, it would just be:
  list[index:index] = [value]
We should have slice assignment!

I looked at the other languages (the ones Sean linked to), and I saw some that
had the same API. So I'm ok with it.
