You can't use (i) in ranges.  $s[(i)ab,(i)fg] is an "invalid subscript";
the end of the range is not treated the same as the start.

So although $s[(r)fg] is the same as $s[$s[(i)fg]], $s[(r)ab,(r)fg] is
not the same as $s[$s[(i)ab],$s[(i)fg]].

The foregoing of course all applies only to indexes on scalars; for an
index on an array, the pattern match and resulting index values apply
to entire array elements, so there are no substrings to extract.
