Design Priorities for the Swift 6 Language Mode

[Douglas_Gregor]

Changing this behavior (no longer propagating the actor isolation to the containing type) would be source-breaking, but there may be ways to mitigate that breakage for particular frameworks (e.g. SwiftUI). But since it's source-breaking, it would need to happen in a new language mode, so Swift 6 would be the right time to do it.

Please do create a proposal for this. I think you have a strong case for removing this inference based on its practical impacts, and it needs to go through the process.
