Sounds like a fun task, but, I'm trying to guess as to what practical use this implementation would be expected to be put? I try to shy away from premature optimization myself, but . . . =) I'd have imagined such a thing would need to be written in "sRuby" (cf. http://www.ce.chalmers.se/~feldt/ruby/ideas/rubyvm/rubyvm.pdf ) to have a chance of being able to be useful for performance reasons. Is there some anticipated use for a regexp-engine-in-Ruby where performance is not a primary concern? Regards, Bill
