Hi, This is on our radar by optimising the lazy-collections <https://github.com/WebKit/JetStream/blob/b7babdf323e64e69bd2f6c376189c15825f5c73a/generators/lazy-collections.js> jetstream workload which covers some aspects of async functions and iterators. If you have a more concrete use-case feel free to add it to JetStream – this is the easiest way for us to pick this up long term.
