Hello,  
I think I’ve spotted a bug in the racket guide, here: [13&nbsp;Classes and Objects](https://docs.racket-lang.org/guide/classes.html?q=Null%3F#%28part._.Traits%29)

It’s about traits.

 ![image](https://global.discourse-cdn.com/free1/uploads/racket/original/2X/0/0b82948e0e190d74d45c1ee79812552546f6fb63.jpeg)

In the marked line _get-color_ and _get-price_ are reversed. Is this a bug?

99% sure it's a bug. (I never used traits.) The file is [https://github.com/racket/racket/blob/master/pkgs/racket-doc/scribblings/guide/class.scrbl](https://github.com/racket/racket/blob/master/pkgs/racket-doc/scribblings/guide/class.scrbl) Do you want to send a PR? If you can't, some of us will fix it (assuming it's a bug).

I know some git, but I’m not good enough to send a PR.

Thanks for your help.

Still 99% sure, so I'm waiting a confirmation.
