Behavior of @ _inheritActorContext in Global vs Instance Actors

I would certainly take just a fix for Task has gotten some traction in the past.

Closure isolation control

Greetings Swift evolvers. For your consideration, I have drafted a proposal allowing for more explicit control over the isolation of closures. You can read the proposal at nnnn-closure-isolation.md Please share thoughts and feedback here or as comments on the pull request. Thank you.

But I really would like to take a closure look at closure behavior more generally, which I don't think can be fixed by a parameter attribute alone. But I've not actually explored changes of that exact nature closely, and I do not know how feasible they would be. And even if they are, you are 100% right that it would be source-breaking, kinda similar to NonisolatedNonsendingByDefault.
