Subtable sort (Was: Length-unaware sorting algorithm)

I've been wondering: why does table.sort not have optional
beginning and starting points?

1. table.concat, table.move, table.unpack all have it.
2. It makes a lot of sense (in fact, many sorting algorithms
operate that way).
3. It is a very easy thing to implement.
4. The maligned concept of length can be sidestepped.
