God damn Haskell

import IO

main :: IO ()
main = do
        putStr "Name: "
        n <- getLine
        putStrLn n


/prog/, why doesn't this code work? I understand laziness, so "n" won't be evaluated until it's needed in "putStrLn", but why does "n" get evaluated, then "putStr" and "putStrLn" get evaulated?

tl;dr How the hell do you prompt for information in Haskell?

I feel kinda bad about OP having his thread ravaged by evil people :( I don't know why am I feeling like this, normally I wouldn't give a damn, but something got me this time.
