async iteration over a ReadableStream containing a rejected Promise will not clean up

3

https://github.com/whatwg/streams/pull/980 defined `Symbol.asyncIterator` semantics for streams, including notably: - breaking out of a `for await` over a readable stream will cancel/release it, and - `for await`ing over a readable stream...

There's been occasional attempts to pass [AstralCodexTen's image generation challenge](https://www.surgehq.ai/blog/dalle-3-and-midjourney-fail-astral-codex-tens-image-generation-bet) (from 2022!), but no one is quite there yet. > 1. A stained glass picture of a woman in a...

https://github.com/tc39/ecma262/pull/3268 lets us simplify use of the iteration protocol.

We got explicit consensus for these rules in the [July 2023](https://github.com/tc39/notes/blob/main/meetings/2023-07/july-13.md#stop-coercing-things), [September 2023](https://github.com/tc39/notes/blob/main/meetings/2023-09/september-28.md#stop-coercing-things-pt-2), [November 2023](https://github.com/tc39/notes/blob/main/meetings/2023-11/november-29.md#stop-coercing-things-pt-3), and April 2024 meetings (notes not yet available for the April 2024). https://github.com/tc39/how-we-work/pull/119 would introduce...

warn for unnecessary emu-not-refs

So they can be linked to instead of just getting the containing clause. Especially after https://github.com/tc39/ecmarkup/pull/441.

get rid of "The order in which module records have their [[AsyncEvaluation]] fields transition to true is significant"

1

[`AsyncModuleExecutionFulfilled`](https://tc39.es/ecma262/multipage/ecmascript-language-scripts-and-modules.html#sec-async-module-execution-fulfilled) sorts a list according to "the order in which [the elements] had their [[AsyncEvaluation]] fields set to `true`". That's pretty wild: it implies you need to keep track of...

The references types proposal landed a couple years ago: https://github.com/WebAssembly/spec/pull/1287 and requires some changes here, for example support for the `externref` value type.
