Includes an else example in the code making it more clear.

Hello. I think generally unless/else is considered an antipattern. Generally speaking if/else is a better choice in my experience, so I'm not sure we want to teach that here. I'd suggest opening a post on the forum (forum.exercism.org) if you'd like to discuss further. Thanks! :)
