  • I should think that Parse::RecDescent would be powerful enough to parse bc, and of course the Perl backend would not be an issue. :-)
    • Sure,but a couple of things speak against PRD:
      • The last update was 2 years ago
      • Not a large user base
      • AFAIK, no direct support for generating ASTs
      • AFAIK, no TreeParser
      /* */
      • The first point shouldn't matter. Parse::RecDescent is very good. -- The three others are true, however, and afaik (at least the user base isn't as large as ANTLR's one.)
