Clippy works as a *plugin* to the compiler, which means using an unstable internal API. We have gotten quite good at keeping pace with the API evolution, but the consequence is that clippy absolutely needs to be compiled with the version of `rustc` it will run on, otherwise you will get strange errors of missing symbols."""
