-Zij gegeven de volgende functie-definities:
-
-subs             :: [a] -> [[a]]
-subs []          = [[]]                              (1.)
-subs [x:xs]      = subs xs ++ map (cons x) (subs xs) (2.)

-map f []         = []                                (3.)
-map f [x:xs]     = [f x : map f xs]                  (4.)

-cons x xs        = [x : xs]                          (7.)

-Bewijs de volgende stelling voor alle functies f en eindige lijsten xs:
-
-    subs (map f xs) = map (map f) (subs xs).
-
-Je kunt gebruik maken van de volgende hulpstellingen (lemma's) die gelden voor alle
-functies f, g en eindige lijsten xs en ys:
-
-map f (xs ++ ys)       = map f xs ++ map f ys        (8.)
-map g (map f xs)       = map (g o f) xs              (9.)
-(cons (f a)) o (map f) = (map f) o (cons a)          (10.)
-(g o f) x              = g (f x)                     (11.)
