@eric.kolotyluk: Regarding collections, I also came to Kotlin from Scala (and Java) and thought I'd desperately miss Scala's immutable collections - so much so I ported them to Java and Kotlin (https://github.com/andrewoma/dexx/tree/master/kollection). However, I've actually found that I don't use them in Kotlin. My usage is almost always involves building up a collection inside a method and passing it out as a read only view
