Interesting comparison of Optionals and Null in Swift, Scala, Ceylon and Kotlin

I was not sure were to post this. I saw many discussion related to Kotlin language features here, but perhaps Reddit was a better choice? here is the link It is interesting how Kotlin looks similar to Swift

Given that the nullability syntax in Kotlin appeared before anyone outside Apple knew of Swift's existence, and didn't change much since then, I think that "Swift looks similar to Kotlin" would be a better way to phrase this. :)

Yes, that is what I actually meant. Kotlin rocks!
