print("Hello, World!")

  Hello world should look something like this: print(“Hello, World”!)

  You don’t need the annotation line in Haskell-esque languages, most of the time. Without the annotation, this is Hello World in Haskell:

  main = print "Hello, World!"
  

  And when you need more complexity, it can still be far simpler than Unison (or Haskell)

  import qualified Data.List as List
  import Data.Function ((&))
  
  processNumbers numbers =
      let
          isEven n = mod n 2 == 0
      in
      numbers
          & List.filter isEven
          & List.map (^2)
  
  main =
      processNumbers [1, 2, 3, 4, 5, 6]
          & print
