You beat me to it. What I love about the Haskell version is it says only exactly what needs to be said. sayHello - get the hello message for something.
putStrLn - send something to stdout
mapM_ - Do these things in sequence, I don't care about the result. Together they say take a list of people, get their greeting strings and print them to stdout in order. It's hard to say it more succinctly without making things confusingly implicit. |
