Here is another one: figure out what `unknown' is.
unknown = mysterious unknown
mysterious ks = 0 : weird ks weird (k : ks) = (k + 1) : mysterious ks
Cool! That leads me to this contraption:
tricky = 0 : enigma tricky tricky enigma (k : ks) = (k :) . labyrinth (enigma ks) labyrinth f (k : _ : ks) = (k + 1) : f ks
Figure out what `tricky' is, and what its relationship is to `unknown'. Enjoy! Matt Harden
