Last year, I tried to port a 100-line Python scraping library to Rust, and couldn't get it working. Today I had Claude take a whack at it... and it worked on the first attempt.

Interesting Rust semver hazard: if you're not `warn(unnameable_types)`, you could be leaking private dependencies via fields in types that are unnameable but can be reached, and this won't be detected by tools based on rustdoc-types (like cargo-check-external-types).
