The key changes are: - Function output parameters are now prefixed with `out`, and more consistently formatted as named parameters. - Function and inst output arguments are now written as part of the inst form, rather than as one of the inst arguments. As a drive-by fix, this also changes `Temporary::storage_id` from `DestInstId` to `InstId`, because it doesn't represent an output parameter of the `Temporary` inst itself. See the review of [#6532](https://github.com/carbon-language/carbon-lang/pull/6532) and [this Discord discussion](https://discord.com/channels/655572317891461132/999638000126394370/1458268977020141589) for additional background.
