I think this is same as issue34616 . The issue talks about the workarounds IPython has to use for the feature and links to the PR where it was implemented https://github.com/ipython/ipython/pull/11265 . I never knew about this feature and this will be very helpful to have especially it reduces boilerplate in having async functions for await calls though asyncio.run improved setting up loop part. Helps in playing around with API in repl during learning with top level await expressions allowed in repl.
