+/**
+ * Builds a list from a seed value. Accepts an iterator function, which returns
+ * either false to stop iteration or an array of length 2 containing the value
+ * to add to the resulting list and the seed to be used in the next call to the
+ * iterator function.
+ *
+ * The iterator function receives one argument: *(seed)*.
+ *
+ * @func
+ * @memberOf R
+ * @since v0.10.0
+ * @category List
+ * @sig (a -> [b]) -> * -> [b]
+ * @param {Function} fn The iterator function. receives one argument, `seed`, and returns
+ *        either false to quit iteration or an array of length two to proceed. The element
+ *        at index 0 of this array will be added to the resulting array, and the element
+ *        at index 1 will be passed to the next call to `fn`.
+ * @param {*} seed The seed value.
+ * @return {Array} The final list.
+ * @example
+ *
+ *      const f = n => n > 50 ? false : [-n, n + 10];
+ *      R.unfold(f, 10); //=> [-10, -20, -30, -40, -50]
+ * @symb R.unfold(f, x) = [f(x)[0], f(f(x)[1])[0], f(f(f(x)[1])[1])[0], ...]
