I think so rules describing ranges and multirages are long enough, so
increasing functionality doesn't look like a practical idea.

I prefere special simple composite type like you described in the previous
email (start, stop) or (start, length). It can be used more times when
using range or multi range is not practical.

The composite types are more natural for this purpose than 2D arrays.
