/**
 * A helper function that wraps an array or an object of functions with `reflect`.

 * @memberOf module:Utils
 * @method
 * @see [async.reflect]{@link module:Utils.reflect}
 * @category Util
 * @param {Array|Object|Iterable} tasks - The collection of
 * [async functions]{@link AsyncFunction} to wrap in `async.reflect`.
 * @returns {Array} Returns an array of async functions, each wrapped in
 * `async.reflect`
 * @example
 *
 * let tasks = [
 *     function(callback) {
 *         setTimeout(function() {
 *             callback(null, 'one');
 *         }, 200);

 *         // do some more stuff but error ...
 *         callback(new Error('bad stuff happened'));
 *     },
 *     function(callback) {
 *         setTimeout(function() {
 *             callback(null, 'two');
 *         }, 100);
 *     }

 * async.parallel(async.reflectAll(tasks),

 *     // results[0].value = 'one'

 * // an example using an object instead of an array
