But that's exactly what typed throws do?

`static func validate(name: String) throws(ValidationError)`

Would be handled as:

```

do {

    try UsernameValidator.validate(name: name)

} catch {

    switch error {

    case .emptyName:

        print("You've submitted an empty name!")

    case .nameTooShort(let nameLength):

        print("The submitted name is too short!")

    }

}

```
