Any plans to implement Asynchronous Invocations like the AWS Lambda API?

Calling one serverless function from another means paying double for the time both are running. It would be cool to have some kind of asynchronous invocation like AWS Lambda has.

From blog article "Is it ok to call one Lambda function from another?"

The invoke operation of the Lambda API also supports asynchronously invoking a function.

By doing this, apiHandler1 from our earlier example would receive an immediate acknowledgement and asynchronously invoke dataProcessor1, allowing the API call to return quickly to the user and stop the billing clock. Also, if dataProcessor1 fails, then AWS will automatically retry the invocation twice and then route it to a dead letter queue if you so wish.
