Now that PEP 654 (ExceptionGroups and except*) is close to done (thank you Irit!), what are the next steps for asyncio? My understanding is that PEP 654 is a blocker for
TaskGroup. Will there be a PEP for
TaskGroup, or is it only a PR?
I personally would like to see mainly the following:
- An addition of a function similar to
gather()that cancels the other tasks when one task raises an exception. This was originally a bug report against
gather(), and was rejected.
I speak as a CircuitPython core developer.
except* may not get into MicroPython (our primary source for core language features) any time soon. Nevertheless, we’d like to provide additions to our own
asyncio that mimic upcoming CPython asyncio features, so we’d very interested in upcoming specs.
