+ * Logs the result of an [`async` function]{@link AsyncFunction} to the
+ * `console` using `console.dir` to display the properties of the resulting object.
+ * Only works in Node.js or in browsers that support `console.dir` and
+ * `console.error` (such as FF and Chrome).
+ * If multiple arguments are returned from the async function,
+ * `console.dir` is called on each argument in order.

+ * // in a module
+ * var hello = function(name, callback) {
+ *     setTimeout(function() {
+ *         callback(null, {hello: name});
