> println! is a macro, and doesn't "break the tooling"

I like, use, and write macros, but this isn't fully true. For example, recent Rust versions allow writing identifiers directly in the format string:

    println!("{some_identifier}")

However, this breaks rust-analyzer's ability to rename variables [1].
