Especially since the second example only gives you a stringly-typed error.

If you want to add 'proper' error types, wrapping them is just as difficult in Go and Rust (needing to implement `Error` in Go or `std::Error` in Rust). And, while we can argue about macro magic all day, the `thiserror` crate makes said boilerplate a non-issue and allows you to properly propagate strongly-typed errors with context when needed (and if you're not writing library code to be consumed by others, `anyhow` helps a lot too).
