I agree that non-zero based arrays can result in much cleaner code in
some cases.

But I think it has to be bundled with another feature: the use
of other types than int as array indexes.

I don't think that it is desirable or likely to shoehorn into
Java at this time.

If one want it then I suggest Ada and JGnat!
