Can I ask what you mean when you say that async isn't done? async/await and Futu...

The team itself described the stabilization of async/await as being in an "MVP" state. Stuff that's been fixed since then:

* error messages (I think there may be more to do, but they're better and better all the time)

* size of tasks (Still more to do, but they've shrunk a lot since it was first implemented

* async/await on no_std (initial implementation used TLS to manage some state, that's since been fixed)

Stuff still to do:

* Async functions in traits (this has a library that lets you work around this with one allocation, having this requires GATs)

* More improvements to the stuff above

* other stuff I'm sure I'm forgetting

> There is no runtime in the core/std but that's by design, there is no short term intent from the Rust team to do that.

This is true but with an asterick; https://github.com/rust-lang/rust/pull/65875 ended up being closed with "please write an RFC," rather than "no."

Huh! Thanks for chiming in and that's good to know!

Side note, I just want to say that I have mad respect for you always finding a way to stay so positive while continuing to be so heavily involved with the community, even with job changes and all of that stuff going on. You're an absolute role model for how to participate in community management and a godsend for Rust.

Thanks. It has taken a ton of work, frankly. I made a conscious decision to try and improve in this way a while back, and while I'm not perfect at it, I'm glad that I'm moving in that direction.
