[issue44604] [Enhancement] Asyncio task decorator to provide interface to define async DAGs (similar to dask's delayed interface)

Hi Yury, could you by any chance point me to some material on the inclusion of task groups in 3.11? I've found these "task group" docs from a library called AnyIO: https://anyio.readthedocs.io/en/stable/tasks.html.

If the asyncio task group feature is similar to this, then while I think it is a nice inclusion, I believe it does not cover the use case that this proposal would cover.

* If your opinion on the matter is still not final, then would you be open to a further demonstration of this proposal? I could gather several use cases from SO and other sites and demo how they could be elegantly solved with this interface.
