| 9 | +Hello! Did you know that the [lang team] now has regular design |
| 10 | +meetings? We use these meetings to dig deeper into the output of |
| 11 | +active project groups. After the meeting, we typically post a |
| 12 | +recording to [YouTube] as well as some [minutes into the lang-team |
| 13 | +repository][min]. I wanted to write a quick update listing out some of |
| 14 | +the meetings we've had recently as well as some of our upcoming |
| 15 | +meetings. |

| 21 | +### Recent lang-team design meetings |
| 22 | + |
| 23 | +We recently held two lang-team design meetings: |
| 24 | + |
| 25 | +* The **const evaluation project group** discussed the overall state |
| 26 | + of const evaluation and a ["skill tree"] that they've been |
| 27 | + developing to show **what some of the next steps are** and how they |
| 28 | + relate to one another. We also discussed **what "unsafe" might mean |
| 29 | + in a const evaluation context** and in particular [Ralf's proposal to |
| 30 | + consider "things that may not be const-evaluable" as "unsafe" in a |
| 31 | + const fn][ralfj]. |
| 32 | + * [Minutes][m1], [recording][r1] |
| 33 | +* Safe transmute project group: We discussed the approaches explored |
| 34 | + by the safe transmute group, and in particular did a bit of a deep |
| 35 | + dive into the [exciting `typic` crate][typic] being developed by |
| 36 | + [jswrenn]. We looked at what it might make sense to pursue as an |
| 37 | + immediate RFC and what ought to stay in the realm of library experimentation |
| 38 | + for the time being. |
| 39 | + * [Minutes][m2], [recording][r2] |

| 50 | +### How lang-team design meeting proposals work |
| 51 | + |
| 52 | +Every proposed meeting begins with an issue on the lang-team |
| 53 | +repository. If you're curious, you can take a look at the [open issues |
| 54 | +with the `meeting proposal` label][mp] to get an idea of what |
| 55 | +meetings are being considered; if a meeting has been scheduled, it |
| 56 | +will also be tagged with [`meeting scheduled`][ms] and have some comments as |
| 57 | +to the current date. |
| 58 | + |
| 59 | +[mp]: https://github.com/rust-lang/lang-team/issues?q=label%3Ameeting-proposal |
| 60 | +[ms]: https://github.com/rust-lang/lang-team/issues?q=label%3Ameeting-scheduled |
| 61 | + |
| 62 | +We currently schedule meetings in a rather ad-hoc fashion, basically |
| 63 | +hammering it out over Zulip. I'd probably like to move us to a more |
| 64 | +"regularly scheduled" scheduling meeting, like the compiler team, but |
| 65 | +we haven't adopted such a scheme yet. |
| 66 | + |
| 67 | +Anyone can propose a design meeting, though they are meant to be |
| 68 | +proposed mostly in conjunction with active project groups or other |
| 69 | +ongoing discussions, and not just out of the blue. Moreover, anyone is |
| 70 | +welcome to listen in on a design meeting, though you should be aware |
| 71 | +that the meeting is typically being recorded. Zoom links are available |
| 72 | +upon request. |
| 73 | + |
| 74 | +### Upcoming lang-team meeting proposals |
| 75 | + |
| 76 | +We currently have two pending lang-team meeting proposals: |
| 77 | + |
| 78 | +* A proposal to discuss the path to lang-team membership ([rust-lang/lang-team#32]). |
| 79 | +* A proposal to discuss enforcing bounds on type aliases and how we |
| 80 | + might phase that in ([rust-lang/lang-team#25]). |
| 81 | + |
| 82 | +We expect to be scheduling those soon, and we'll update the issues |
| 83 | +with dates when they are available. |
