java.lang.IllegalArgumentException: Wrong number of args (3) passed
to: user$spel-print (NO_SOURCE_FILE:0)

there is a well in front of you -)
(east door living-room))
'attic '((you are in the attic of the

(first (location game-map)))
;; in clojure backquote mode, the ~ escapes the mode instead of the
comma
(defn describe-path [path]
