[Haskell-cafe] csv one-liner

[wman]

Thanks a lot, I've had a hunch it was possible to get rid of those those
liftM's. I turned it into:

(writeFile "output.csv") . printCSV . (map updateLine) . (either (error
"Chyba pri cteni CSV.") id) =<< parseCSVFromFile "input.csv"

and am sincerely hoping he will try to decypher it's meaning ;-)))
