replicateM_ 100 $ do
getLine
print $ best pole 42 420

Hello all,
I have a haskell program that runs an order of magnitude slower
when compiled with optimisations turned on. This happens on 6.8.2
as well as 6.10.1:
p...@r4at184:/tmp[1]% ghc --make -fforce-recomp -o out buga.hs
[1 of 1] Compiling Main ( buga.hs, buga.o )
