Odersky and team created very ergonomic and beatiful compiler with support of macroses. After working with Rust macroses I can say that Scala macroses are much more powerful and easy to use. A lot of work were done to make them ergonomic.
Would be cool to have tool similar to Rust https://insta.rs in Scala 3.
