### (nominated) rust.tf/libs403 *Add \`RawStatusCode\`*
Mara: It's just a type alias and no other API? I don't think it should exist if we don't also ship an exit() api that takes this type.
Amanieu: It could be an extension trait on ExitStatus
David: ExitStatus can have a method that returns a larger integer. compatible with other platforms just fine.
Mara: Seems fine to have a .code64() or w/e
Amanieu: Disagree. Nobody will call that unless they specifically expect a large exit code.
David: How confident are we that *every* non-UEFI platform will use i32?
Josh: Aliases that change meaning per platform are painful
Mara: +1. prefer extension trait or new method.
Josh: Prefer extension trait.
The 8482: We already have that for unix.
Josh: For windows too.
Consensus: extension trait for uefi.
Josh to reply.
### (nominated) rust.tf/75744 *Tracking issue for \`ControlFlow\` enum, for use with \`try\_fold\` and in \`Try\`*
Just asking for input on new methods. Not a stablization or anything like that.
Mara: Naming seems fine.
Josh: do we have other `_value` names in std?
Josh: This shouldn't have as many helper methods as Result/Option.
Amanieu: ControlFlow doesn't need short names.
Consensus: fine as is, as unstable.
Mara replied.
### (nominated) rust.tf/rfc3672 *RFC for project goals*
### (waiting on team) rust.tf/119550 *Rename \`AsyncIterator\` back to \`Stream\`, introduce an AFIT\-based \`AsyncIterator\` trait*
WG-async
### (waiting on team) rust.tf/124941 *Stabilize const \`{integer}::from\_str\_radix\` i.e. \`const\_int\_from\_str\`*
In FCP
### (new change proposal) rust.tf/libs406 *Make \`proc\_macro\` available outside procedural macro generation*
Waiting on author
### (new change proposal) rust.tf/libs410 *Change \`std::fs::remove\_dir\_all\` to be idempotent*
The 8472: ACP is a breaking change.
The 8472: alternative: https://github.com/rust-lang/rust/pull/127623/files
Mara: I think accepting the ACP might be fine. Behaviour makes sense. But rejecting the ACP and accepting that PR is also fine to me.
Amanieu: Let's merge the PR and close the ACP.
Mara: +1
Josh: +1
Amanieu to reply
### (new change proposal) rust.tf/libs411 *ACP: add \`std::any::is\_same\_type::\<T, U\>() \-\> bool\`*
Propose `.is::<T>()` instead.
Amanieu to reply
### (new change proposal) rust.tf/libs412 *File lock API*
### (new change proposal) rust.tf/libs413 *ACP: add bitwise/bytewise methods to NonZero*
### (stalled change proposal) rust.tf/libs176 *\`Peek\` trait for peekable iterators*
### (stalled change proposal) rust.tf/libs271 *Unix Domain Sockets on Windows*
### (stalled change proposal) rust.tf/libs124 *Integrate \`Error\` trait with panic interfaces*
### (stalled change proposal) rust.tf/libs111 *Restructure ptr\_metadata to minimal support*
### (stalled change proposal) rust.tf/libs181 *\`Cow::map\_borrowed\`, \`Cow::map\_owned\`, and \`Cow::map\`*
