   > the function for the resulting task will always have the same id
   
   This isn't true @potiuk.
   
   For example
   
   ```python
   with DAG(dag_id='x'):
       @task
       def foo():
           ...
   
       foo()
       foo()
       foo()
   ```
   
   will result in tasks with IDs of `foo`, `foo__1`, `foo__2` etc, and is tested.

   @sjacquot Also in that example is a test of doing this in a task group.
   
   If it is not behaving, the first step would be to create a failing test case we can put in our unit tests.
