Sorry, but you can't execute another s/// without /e, (?{}) or (??{}).
Since the regex engine isn't re-entrant, I can't execute another s/// even with /e, (?{}), or (??{}), right?

    That is my understanding. You can have recursive patterns, but I don't think you can enter another match when one is already in progress.
