I work on a reasonably large Django project (1M+ LOC) with approximately 100 developers and mostly have a reasonable time debugging. We use mypy, lots of linters (some custom flake8 plugins), and a fairly strict layered architecture[0] that's enforced with tooling[1].
Without the tooling it's a nightmare. My previous Django project with approx 500k LOC had linting and some typing and that was a mess.

About this new asyncio.TaskGroup thing, I found this from Guido on the related GH issue*
> After some conversations with Yury, and encouraged by the SC's approval of PEP-654, I am proposing to add a new class, asyncio.TaskGroup, which introduces structured concurrency similar to nurseries in Trio.
I have never used but have been told that Trio's nurseries make it much easier to handle exceptions in asyncio tasks. Does someone more knowledgeable can tell if this will help? Looking at the docs*, this only seems to be a helper when you want to await several tasks at once, so I am not sure this changes much for exception handling.

Flake8
flake8 is a python tool that glues together pycodestyle, pyflakes, mccabe, and third-party plugins to check the style and quality of some python code.
That probably won't happen any time soon.
See https://github.com/PyCQA/flake8/issues/234#issuecomment-1206...

While it's of course not ideal, stub files can help with this issue. For example you can get stubs for Celery that make both `shared_task` and `delay` properly typed: https://github.com/sbdchd/celery-types

Using mamba to create a new encoding called py311 with python 3.11:
mamba create -n py311 python=3.11 -
> Yes, there are type stubs for these libraries but they’re either forced to be more strict, preventing use of dynamism, or opt for being less strict but allowing you to use all the library features, at the cost of safety.
There are type stubs for Django that somewhat avoid these compromises: https://github.com/typeddjango/django-stubs
To be able to do this they have to use a Mypy plugin though. And even then it's still far from perfect.

I'm worried about the speedup
My understanding is that it's based on the most recent attempt to remove the GIL by Sam Gross
https://github.com/colesbury/nogil
In addition to some ways to try to not have nogil have as much overhead he added a lot of unrelated speed improvements so that python without the gil would still be faster not slower in single thread mode. They seem to have merged those performance patches first that means if they add his Gil removal patches in say python 3.12 it will still be substantially slower then 3.11 although faster then 3.10. I hope that doesn't stop them from removing the gil (at least by default)
