Anything else?

No response

Reproduce the example in src/main.rs with the reported Rust nightly and compare the current and desired E0277 diagnostics. Trace the compiler diagnostic path that emits the borrowing suggestion, then add a regression test covering the reference location and verify the suggestion matches one of the desired outputs.
