1.7 Hangman: "hangman.ss"

The teachpack implements the callback functions for playing a Hangman game, based on a function designed by a student. The player guesses a letter and the program responds with an answer that indicates how many times, if at all, the letter occurs in the secret word.

The teachpack provides all the drawing operations from Simple Drawing: "draw.ss" for managing a canvas into which the “hangman” is drawn.

(hangman make-word reveal draw-next-part)  true
  make-word : (-> symbol? symbol? symbol? word?)
  reveal : (-> word? word? word?)
  draw-next-part : (-> symbol? true)
Chooses a “secret” three-letter word and uses the given functions to manage the Hangman game.

(hangman-list reveal-for-list    
  draw-next-part)  true
  reveal-for-list : 
(-> symbol? (list-of symbol?) (list-of symbol?)
    (list-of symbol?))
  draw-next-part : (-> symbol? true)
Chooses a “secret” word—a list of symbolic letters—and uses the given functions to manage the Hangman game: reveal-for-list determines how many times the chosen letter occurs in the secret word; draw-next-part is given the symbolic name of a body part and draws it on a separately managed canvas.
