gh-115775: Add whatsnew entry about __static_attributes__ by iritkatriel · Pull Request #117909 · python/cpython
Thanks for the description!
I'm not sure what the use case is for adding this as public API. But since it is exposed, I guess it should also be added to the list of special attributes.
(Sorry about the drip-feed of suggestions :( I'm not following the change closely -- I'm just reacting to the effect on projects tested with the latest alpha.)
