Is there a plan to optimize async generators?

[Reve]

async-iterable.ts
Basically I want this:  async function* createAsyncGen(list: Promise<any>[]) { yield* list; } 
But it is 1.4x slower than implementing the iterator protocol manually, which needs way more code

Hi,

This is on our radar by optimising the lazy-collections 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.

Cheers,

Camillo
