What you are saying is you are using yacc to make your coding of a parser convenient. Surely this highlights a deficiency in Perl to be able to express this sort of program? One of the biggest problems with picking a particular language to do your coding in is that certain programming styles suit different languages. For example, you wouldn't want to do systems programming in Prolog any more than you would write a complex context free grammar using m// and if(). Surely, we want Perl to be good at writing any sort of program, be it one that suits a procedural, OO, functional or rule based programming style. Or other programming styles I don't know about. What is yacc, but a rule based language plug-in for procedural languages? Why limit Perl to OO and procedural programming at its core? Sam.
