Subject: Re: Parser generator

I really doubt that scripting languages offer faster implementation of
complex algorithms then C (which has bison/lex etc.)

All parsers i've seen so far that are written in python, are
really bad, trying go do things with regular expressions that can't be
done (context free regular expressions are not very powerful - read
the non political literature from Chomsky). In fact is there a MIME
parser that is written correctly in a scripting language ? For Perl and
Python the answer is no. I had to go to C++ to get one.

And do you want only a lexical parser or also one that gathers semantic
information about ruby code ?
