@<1523701435869433856:profile|SmugDolphin23> Yeah, I just wanted to validate it was worth spending the time. Since there is already a parameter that takes callable (i.e. schedule_function ) it might make sense that we reuse the parameter. If it returns a str we validate that it's a task and if it does we can run the task as if we originally passed it as the task_id in .add_task() . This would only be a breaking change if the callable that was passed happened to return a task_id . Or do you think it would be better just to add a new parameter?
