[Haskell-cafe] Re: Progress on shootout entries

[Kimberley Burchett]

I took a quick crack at optimizing fannkuch.hs.  I got it down from 33s to 
1.25s on my machine, with N=9.  That should put it between forth and 
ocaml(bytecode) in the shootout page.  The main changes I made were using 
Int instead of Int8, foldl' to accumulate the max number of folds, a 
custom flop function rather than a combination of reverse and splitAt, and 
a simpler definition for permutations.
