- replaced `match`s with `?`s where possible
- it should not be considered an improvement tho
- turns out `?` is best used when you are returning `Result<T,E>`s
- we were returning `String`s
- so we had to wrap all successful string returns in `Ok()`s
- which is just clunky
- good learning but its time to move on!
- finally get an error handling example running the way it should
- we've used the ugly method (a lot of matches and so on)
- and our code is not beautiful per se
- but it works
- next we improve this with `?`s
