First of all, instead of "sequence_ $ map ..." use "mapM_ ...", which is the same thing but nicer. Now, have you tried "mapM_ (trialLoop gain tolerance joy) (take 2 $ trialList ps)"? That should be the same as those two lines you wrote. I am suspecting here that your program is hanging only with mapM_ because of some of the trials that are not the first two. HTH, -- Felipe.
