[Haskell-cafe] Re: Returning a list element?

I argue if you want to sequence_ a map you should write mapM_:

mapM_ putStrLn ["line1", "line2", "line3"]

Nice

mapM is under-appreciated? More under-appreciated are line gaps:

main = putStr "line1\n\ \line2\n\ \line3\n"

Or if you don't like hand writing in all the newlines you could use putStrLn . concat . intersperse "\n"
