@mcollina PTAL when you have time. No hurry.

There are 3 tests that I have commented out which fail. These failures seem to be related to difference between how an async iterator from an async generator i.e. async function* works and how our custom async iterator works. I would guess that the behavior from async generator should be more spec compliant? Or maybe it's a timing issue? Either way probably a semver-major.

  1. the async iterator prototype test.
  2. next promises are not rejected, but instead resolved

@nodejs/tsc @mcollina @benjamingr I defensively marked this as semver-major. However, it would be nice to land this on v14 as it might become the basis for future semver-minor changes.

I concur with @ronag. We might want to land this on v14 before it goes to LTS.

@Trott This didn't make it to the tsc agenda this week? I guess it's because the PR is closed?
