Which error message do you find easier to read?

GHC-style:

Hangman.hs:46:32: error:
    * Couldn't match type '[Char]' with 'Char'
      Expected type: Char
        Actual type: String
    * In the first argument of 'makeGuess', namely 'letterInput'
      In the first argument of 'gameLoop', namely
        '(makeGuess letterInput gs)'
      In the expression: gameLoop (makeGuess letterInput gs)
   |
46 |       else gameLoop (makeGuess letterInput gs)
   |                                ^^^^^^^^^^^

Elm-style:

-- Type mismatch ---------------------------------------------------- Hangman.hs

46 |       else gameLoop (makeGuess letterInput gs)
                                    ^^^^^^^^^^^
Couldn't match type '[Char]' with 'Char'

Actual type:

    String

Expected type:

    Char
