Comment:
For the record, I tried updating this PR to rust-analyzer 2022-01-17, but it fails to build because we don't have Rust 1.58 yet.  As of [two days ago](https://github.com/rust-analyzer/rust-analyzer/commit/91279db2b4dff5cc77a9f34a2212e93490676c46#diff-fe57070ff64dbee9c061031533b3b75f6ef360f3a794aefad62f6849be2caaa3R16) it relies on [captured identifiers in format strings](https://blog.rust-lang.org/2022/01/13/Rust-1.58.0.html#captured-identifiers-in-format-strings).  We could probably update to 2022-01-10, but hopefully we have Rust 1.58 soon.
