## Proposed meetings

- "Language design principles" [lang-team#189](https://github.com/rust-lang/lang-team/issues/189)
- authors: Niko, Josh
- would have to be late March to have a chance of getting done
- "Design decisions around the `#[expect]` attribute" [lang-team#191](https://github.com/rust-lang/lang-team/issues/191)
- we don't know if xFrednet is available or interested in authoring a doc
- nobody else has time to write it
- "discuss/resolve `fn { mod { (use) super::...; } }` and its interaction with derive patterns" [lang-team#193](https://github.com/rust-lang/lang-team/issues/193)
- Tentatively February 15 - compiler team considers this urgent
- "Design Meeting: Field Projection" [lang-team#194](https://github.com/rust-lang/lang-team/issues/194)
- y86-dev proposed to discuss it, would prefer March or later
- async wg did a review that raised questions, have those answers been incorporated? unclear. [notes](https://hackmd.io/79TICQb0SPWCIcz02IiWaA?view)
- at minimum, a couple of starting questions to help us focus the discussion
- "Post-monomorphization errors" [lang-team#195](https://github.com/rust-lang/lang-team/issues/195)
- author: tmandry
- try to schedule this for sure
- maybe schedule two dates :)
- "Interface between opsem and lang team" [lang-team#196](https://github.com/rust-lang/lang-team/issues/196)
- authors: jakob degen, ralf, pnkfelix
- "Temporary lifetimes" [lang-team#197](https://github.com/rust-lang/lang-team/issues/197)
- authors: BN (aka [b-naber](https://github.com/b-naber)), oli... niko?
- going in:
- description of the problems
- clear description of how an edition-related change could work to address them
- ideally: we'd describe how to transform existing programs to preserve semantics unambiguously
- goal:
- shared understanding of problem space
- agreement about which of the problems are most important to fix
- ruling out or endorsing some possibilities

Other edition related things:

* IDE-related stuff or stuff that would drive compilation time improvements

## Dates to plan for
