## 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.

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.
