There's only one nitpick I could find in the text: in Rust, semicolons are not delimiters, but instead they distinguish statements and expressions. It's clearest when returning. Rust returns the last value, so `3 + 5`, which evaluates to `8: u32`, is different than `3 + 5;`, which evaluates to `(): ()`. I'm not sure if that makes things better, but it could be worth a special mention.
