Unlike rsplit, this iterator returns split substrings right to left, but other- wise it behaves just like eachsplit. This design has been chosen to avoid either a costly double traversal of the input string, or needing a stack to store the strings. Both of these workarounds would lessen the appeal compared to simply using rsplit.

rsplit? I believe this is unfortunately necessary.
