No, it is not just a build test. Doctests are actually transformed into KUnit tests automatically, and `assert!`s inside them actually report back to KUnit too. It was a major hack to implement, but I am proud of that one :) That also allows us to build them with Clippy, to e.g. get the safety comments right, which is something normal Rust doesn't support yet. We are actually getting a feature from upstream Rust to support it all in a stable and nice way! Cheers, Miguel
