YES! sqlx::query_as in the wild!

Making queries like this checks the sql is valid at compile time by connecting to the real database and running it with demo data inside a rolled-back transaction!

Rust's macro system allows you to program the compiler with each new program, and sqlx is my favourite example of this.
