You may have to slightly update the Scala spec for that 😉. Fair enough, though - I was mainly interested if anyone has proposed before so I don't duplicate. Kotlin is just too lovely of a Scala alternative - it's tempting to write functional in it. Matter of fact, I'm going through "Functional Programming in Scala" using Kotlin, and there's really a lot of non-strict stuff 🙂. Thanks, gents!
