## RFCs to review
https://github.com/rust-lang/rfcs/pulls?q=is%3Apr+is%3Aopen+label%3AT-lang+sort%3Aupdated-desc
## Project goals
https://rust-lang.github.io/rust-project-goals/2024h2/flagship.html
## Retrospectives
- unsafe attributes
- precise capturing
- RFC 3373
- general experiences in the last month
## Plan for two months?
tmandry: We planned for two months last time; how'd we feel about that?
TC: Worked out great. Doing two months gave us some more flexibility on rescheduling for the availability of the item owners. Of course, this relies on having enough things to fill in.
## Project goals
| Goal | Owner | Notes |
| --- | --- | --- |
| *Design meeting* | | |
| ↳ [Async closures](https://rust-lang.github.io/rust-project-goals/2024h2/async.html#ownership-and-team-asks) | [Michael Goulet][] | 2 meetings expected |
| ↳ [Trait for async iteration](https://rust-lang.github.io/rust-project-goals/2024h2/async.html#ownership-and-team-asks) | [Eric Holk][] | 2 meetings expected |
| ↳ [Async drop experiments](https://rust-lang.github.io/rust-project-goals/2024h2/async.html#ownership-and-team-asks) | [Vadim Petrochenkov][] | 2 meetings expected |
| ↳ [Ergonomic ref-counting](https://rust-lang.github.io/rust-project-goals/2024h2/ergonomic-rc.html#ownership-and-team-asks) | [Jonathan Kelley][] | 2 meetings expected |
From [RFC 3672](https://github.com/rust-lang/rfcs/pull/3672).
#### Async closures
Approved RFC; stabilization blocked on bikeshed.
#### Trait for async iteration
There are interesting ordering questions with respect to:
- `unsafe<..>` binders
- `Pin` ergonomics
Late August, early September.
