John M. Dlugosz,
If you haven't already, you might want to read Breaking The Rules II. I know that Marpa is marked alpha but after following the author's blog - I think that has more to do with no guarantee of backward compatability than it does with robustness. If I were starting a new project today, I would likely give it a whirl.

Cheers - L~R

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
