+> It's very much a positive feedback loop: good tooling makes good tooling easier to build, so more of it gets built and the cycle repeats.  
+> `cargo-semver-checks` stands on the shoulders of giants like `rustc` and `rustdoc` and [Trustfall](https://github.com/obi1kenobi/trustfall). Remove any one of them (or even just `rustc`'s high-quality diagnostics!) and `cargo-semver-checks` wouldn't have been a viable project at all.
