We all hope that WWDC 2023 brings a resolution to the incomplete Foundation/concurrency state-of-affairs.

I'm also hoping that some of the async concurrency algorithms get promoted, too (e.g., channels.)

I'm worried, though, that I haven't seem more hints about addressing a few of my pet peeves:

1. The ability to gracefully constrain the degree of actor reentrancy.

2. Some less punitive `Sendable` patterns. (Admittedly, many of these go away once Foundation gets its act together.)
