(defn update-at
  "Takes a structure, a function that returns a list of paths (lists of keys) and a
  function to apply at those paths within the structure.

  For any paths that don't already exist in m, then f will be called with nil
  and that path in the structure will be created with the result."

  (reduce (fn [s v] (update-in s v f))
