## Triage

### (nominated) rust.tf/106541 *implement const iterator using \`rustc\_do\_not\_const\_check\`*

Discussed last meeting. We asked what safety measures are in place to prevent accidentally stabilizing anything.

PR looks fine.

### (nominated) rust.tf/107200 *io: soften ‘at most one write attempt’ requirement in io::Write::write*

The 8472 left a long comment and Josh started FCP last week. No checkboxes checked yet.

Lucretiel left a comment about documenting that write() should never succesfully write some bytes but then also fail afterwards, since that can't be reported. We should indeed clearly document that.

### (nominated) rust.tf/107680 *Hide repr attribute from doc of types without guaranteed repr*

Using `#[cfg_attr(not(doc), repr(transparent))]` to hide `#[repr(transparent)]` from the public documentation.

It should probably do that automatically if there are private fields.

Should we have a `#[repr(transparent, pub)]`? Over an edition? Or just without an edition?

Having `#[repr(transparent)]` in rustdoc today doesn't really give any guarantees, so requiring `pub` for it to display in the docs would be fine.

### (nominated) rust.tf/rfc3362 *Command improvements for ergonomics and error handling*

[discussion]

Seems like it might need to explore a bit more of the design space.
