    Description

      There are several situations where it would be useful to reverse the order of the dataset. This could be done more efficiently than a sort. It would require

      • inline datasets. (These could generally iterate in reverse, imposing no run time overhead)
      • grouped datasets - reverse just within the group
      • local
      • global.

      There is also opportunity for various optimizations - e.g., REVERSE(SORT())->SORT'
