A quick read suggests that it adds negative indexing from the end of the array.

  Imho that violates the principle of least astonishment - that "at" would have such different behavior from "[]" for negative numbers.

    That's the whole point of this though... Currently you can't use negative indexes, but this would make them usable.

      Oh, I'd assumed main point was to provide a composable function.
