> getLine >>= (return . (++) "Hello, ") >>= putStrLn A pointfree solution - if you want one - would be more in the form of: getLine >>= putStrLn . ("Hello, " ++) It's really mostly about getting used reading pointfree style, but there's certainly an overuse of pointfree style in some Haskell code, then it gets pointless.
