I tried it after working with m/\G/gc regex first. I was surprised how easy it was converting my regex to a Parse::RecDescent grammar. I have begun to see where the talk in perl6 about rules rather than regex is coming from. I like the feeling in perl of being able to pull yourself up by your bootstraps, learning as you go. At the same time, I wonder why whatever I read in the perl5 stuff never tried to lead me across the bridge from regex. Now I'm reading Dick Grune's online book about parsing. I've only written one simple grammar. The feeling of mastery however is motivating. I think I will be on the lookout for ways to parse more things from now on. All this was generated by my first simple parsing need, however, of course.
