-- The type `IO` is an example of a "monad". The way Haskell uses a monad to do IO allows it to
-- be a purely functional language. Any function that interacts with the outside world (i.e. does IO)
-- gets marked as `IO` in its type signature. This lets us reason about what
-- functions are "pure" (don't interact with the outside world or modify state)
-- and what functions aren't.
