      * @method memoize([fn])
      * @returns Function
      * @short Creates a function that will cache results for unique calls.
-     * @extra %memoize% can be though of as a more power %once%. Where %once% will only call a function once ever, memoized functions will be called once per unique call. A "unique call" is determined by the result of [fn], which is a hashing function. If empty, [fn] will stringify all arguments, such that any different argument signature will be unique.
