- DOM Parts, especially goals and constraints. Chrome's experimentation is ongoing, but so far a native implementation doesn't look like a slam-dunk performance win. Are there DX goals that justify the feature, or higher level features (like templating) that we should pursue?

- Concurrency Control Presenter: MF and LCA
  - Async Iter Helper で Concurrency を分離した
    - concurrency control
    - unordered async iterator helpers
  - その片割れ
  - Governor とは??
    - Mozilla と Igalia が懐疑的
- unordered async iterator helpers for Stage 1
Iterator Helper の concurrency じゃない方の片割れ
AsyncIterator.prototype.unordered から別の世界に分岐する
- Normative: fully define Math.sqrt
https://github.com/tc39/ecma262/pull/3345
Implementation Approximate
仕様ではなく実装で精度が決まっている
これを仕様側で精度を決めるように
きっかけは WASM
- Error.isError for Stage 2.7
Array.isArray は Array を Proxy してるものも判定するが
Error はそうではない
- これが Piercing
次回 2.7 にしたいかも
