Omitted bounds are common in other languages and would be handy. I don't think they'd cause any issues with multi-dimensional arrays or variable start-pos arrays.

I'd love negative indexes, but the variable-array-start (mis)feature means we can't have those. I wouldn't shed a tear if variable-start-position arrays were deprecated and removed, but that's a multi-year process, and I'm not convinced negative indexes justify it even though the moveable array start pos feature seems little-used.
I'm all for ditching variable start, full stop.
Since the start-pos is recorded in the array, I wonder if it's worth supporting negative indexing for arrays with the default 1-indexed element numbering, and just ERRORing for others. Does anyone really use anything else?
