    any of the subscript expressions are null.  However, in other corner
    cases such as selecting an array slice that
    is completely outside the current array bounds, a slice expression
!   yields an empty (zero-dimensional) array instead of null.
    If the requested slice partially overlaps the array bounds, then it
    is silently reduced to just the overlapping region.
