A mandatory smart-ass Haskell response

    import System.Environment (getArgs)
    main = do
      [str] <- getArgs
      putStrLn $ take 12 str

[nicolast]

Now with more operators!

    import System.Environment (getArgs)
    main = putStrLn =<< take 12 . head <$> getArgs

;-)

The actual smart-ass haskell response is simply "take 12". The spec didn't specify this needed to be a impure shell command, so a pure function is obviously better.

Well, for smart-ass (and I know you meant it as a joke) is not very impressive. Don't do anything more than the others, and the syntax is not so great either.

On the contrary, his is the only one that crashes when more arguments than expected are passed. Hooray progress!
