module Y2017.M11.D02.Exercise where
Here's a simple Haskell exercise for you on All Souls' Day.
Create an application, call it im, that takes as arguments your name and
replies with a friendly greeting.
For example:
$ im geophf
Hello, geophf, how are you?
$ im
What? You're what? Are you going to tell me your name or what?
... something like that.
main' :: [String] -> IO ()
main' name@(_:_) = undefined -- greet name
main' [] = undefined -- prompt for name
-- Now, at the top level directory have a module, call it Main, that calls
-- this main' function with the command line arguments.
-- There you go. Bob's your uncle.
