Here are three questions:


Q1: Is there any parser generators, yacc-like, that will produces
        parsers with driver in PERL and will take actions in PERL ?


Q2: If yes, where to find it ? Is it an LALR, LR, or LL parser
        generator ?


Q3: If no, what about the idea of writing such a parser generator ?
        What will be the potential difficulties ? Does anyone already
        has such a plan ?


Your comments are appreciated. Please post them here or mail to me.


Thank you very much.
[I'd think it'd be straightforward to modify Berkeley yacc to produce its
parser in perl rather than C. Yacc used to do ratfor, after all. -John]
