[External] : Re: Ephemeral threads

[Remi Forax]

While it makes sense to see Java coroutine as Thread, it makes less sense to see generators as Thread.

So if we introduce generators, we will use a different mechanism than virtual threads,
so the expectations are not the same, so most of the spooky issues discuss here do not exist.
