btw, JHC's version of FPS uses slightly less memory (i don't remember,
8 or 12 bytes per each string) and i think must be faster (because it
uses ByteArray# instead of Addr#). so, the best variant is to add hGetLine
to John's library

(arr,x) =: yv

looks better ;)

you are definitely a Hal Daume's client, look at http://www.isi.edu/~hdaume/STPP/
