Wow, I didn’t realize that the highlighted sections were links to source, that is great! It also explains what happened to cause the errata in [my post](https://forum.devtalk.com/t/hands-on-rust-beta-2-trimming-input-page-25/4420). Looks like the source code changed but the book didn’t. I agree, calling this convention out more explicitly would be useful.
