 - Print the final output of a macro using `cargo rustc --profile=check -- -Zunstable-options --pretty=expanded`
  - Alternatively you could install and use [cargo expand](https://github.com/dtolnay/cargo-expand) which adds syntax highlighting to the terminal output.

 - Print output during macro compilation using `eprintln!("hi");`
