;; YIKES! you clearly wrote the function before the tests, because what you have below
;; is just nuts.  Specifically, you have a table that maps strings to ... tables!
;; Let's rewrite those test cases first:

(check-expect (add-stat (add-stat (hash) '("a" "b" "c")) '("a" "b" "d"))
              (hash "a" 2 "b" 2 "c" 1 "d" 1))
