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 [http://codemonkeyism.com/comparing-optionals-and-null-in-swift-scala-ceylon-and-kotlin/](http://codemonkeyism.com/comparing-optionals-and-null-in-swift-scala-ceylon-and-kotlin/) 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!
