You also could if array[5 .. -3] implied length -3.<BR>

Similarly. array[-3] could imply array[array.length -3]...<BR>
<BR>
But someone suggested against that, atleast for non-compile time checking. I would agree, for the non-literal instance that a negative integer of -5 shouldn't result in magical figuring out if the element needs to be pulled from the front or the back. But the literal case adds expressiveness, I think.<BR>
