** Script Error: Invalid argument: ?native?
words in parse are meant to be other blocks for sub-parserules.
so [reverse[hello"]] is invalid.
usually one could try to use compose before, but then
the compose-marking brackets are also used by parse itself.
so composing parse-expressions is difficult.
