- * A close relative of [`retry`]{@link module:ControlFlow.retry}. This method
- * wraps a task and makes it retryable, rather than immediately calling it
- * with retries.
- *
- * @name retryable
- * @static
- * @memberOf module:ControlFlow
- * @method
- * @see [async.retry]{@link module:ControlFlow.retry}
- * @category Control Flow
- * @param {Object|number} [opts = {times: 5, interval: 0}| 5] - optional
- * options, exactly the same as from `retry`, except for a `opts.arity` that
- * is the arity of the `task` function, defaulting to `task.length`
- * @param {AsyncFunction} task - the asynchronous function to wrap.
- * This function will be passed any arguments passed to the returned wrapper.
- * Invoked with (...args, callback).
- * @returns {AsyncFunction} The wrapped function, which when invoked, will
- * retry on an error, based on the parameters specified in `opts`.
- * This function will accept the same parameters as `task`.
- * @example
- *
- * async.auto({
- * dep1: async.retryable(3, getFromFlakyService),
- * process: ["dep1", async.retryable(3, function (results, cb) {
- * maybeProcessData(results.dep1, cb);
- * })]
- * }, callback);
