Going over Rust basics, I thought this "loop-break with value" looked interesting and conceptually similar to Scala3's boundary/break. Using ??? Seems to be important, allowing to reduce `T | Nothing` type to just `T`.

moving around And'ed effect requirements. `type And[A, B] = func() (*A, *B)`, since Go lacks Scala3 intersection types.

Sometimes, you have to be honest with yourself! (we still use Options, in Scala3, we should use T|Unset instead, that's for later)

Apache PekkoのTyped Actorを学び直してるのだけど、Akka Classic Actorの悪いところが直っててすごい。デフォルトで再起動ではなく停止するようになったのも良いし、状態更新がapplyのコンストラクタを呼ぶようになったのも良くてめちゃくちゃ使用感が良くなってるな。Scala3ですごく読みやすい。

TIL, in Scala3 (maybe Scala2 too, IDK), you can use `unapply` mechanism in for comprehensions exactly like in pattern matching Useful for some niche scenarios, actually See https://t.co/uyBjsvwqiw
