   Yeah, this is a known problem (well, I know it, at least) with `@task`, you need to instead do something like
   
   ```python
   @task_group
   def do_all_things():
       for i in range(5):
           @task(task_id=f"do_thing_{i}")
           def do_thing(i):
               print(i)
    
           do_thing(i)
   ```
   
   instead. But it’s unfortunately not very easy to fix.
