The interesting thing is speed _and_ safety, I guess. although writing  
fast C on multicore is arguably harder than in Haskell.
The Parsec suggestion is interesting, but from the outside, it  
wouldn't seem significantly different to doing it in C. Maybe if you  
could specify your own grammars from outside? Hm.
