Re: [Haskell-cafe] Lifting makes lazy

This should *not* display anything. Look at the types! displayFile1 returns a value that is the "displaying action". It does not "run" it. Replace "liftM" with "(=<<)" or use "join displayFile1" if you want to run the displaying action. mike

displayFile1 :: IO (IO ()) displayFile1 = liftM putStr contents -- Displays nothing where contents :: IO [Char] contents = readFile "DisplayFile.lhs"

This should display the contents of a file, but nothing appears.
