@karelpeeters This would be forcing to add an else branch in a used when expression and showing a warning in a when statement where there's no else. But I don't think we need this in Kotlin, at least, I didn't need the language to enforce things more than it's already doing. The Swift 4/5 proposal may be overkill for Kotlin
