+ * Version of the compose function that is more natural to read. Each function
+ * consumes the return value of the previous function. It is the equivalent of
+ * [compose]{@link module:ControlFlow.compose} with the arguments reversed.
+ *
+ * Each function is executed with the `this` binding of the composed function.
+ *
+ * @name seq
+ * @static
+ * @memberOf module:ControlFlow
+ * @method

+ * @category Control Flow
+ * @param {...Function} functions - the asynchronous functions to compose
+ * @returns {Function} a function that composes the `functions` in order
+ * @example
+ *
+ * // Requires lodash (or underscore), express3 and dresende's orm2.
+ * // Part of an app, that fetches cats of the logged user.
+ * // This example uses `seq` function to avoid overnesting and error
+ * // handling clutter.
+ * app.get('/cats', function(request, response) {
+ *     var User = request.models.User;
+ *     async.seq(
+ *         _.bind(User.get, User),  // 'User.get' has signature (id, callback(err, data))
+ *         function(user, fn) {
+ *             user.getCats(fn);      // 'getCats' has signature (callback(err, data))
+ *         }
+ *     )(req.session.user_id, function (err, cats) {
+ *         if (err) {
+ *             console.error(err);
