Pattern matching: Kotlin has a `when` that desugars into if when statements, but it's pretty far from pattern matching like you see in Scala, Swift, and more traditional functional languages. Recursive data structures: Yeah, for some reason I wrote recursive data structure when I was thinking of algebraic data types, like Scala can encode with case classes. I often use them in Scala or OCaml to make recursive data structures which is why I mistakenly used that term instead of ADTs. TCO: glad to see I was wrong. Kotlin added support for this in the past year. Android: I realize that to support Swift on Android, Google would need to do significant work, but they wouldn't have to change the VM since Swift could also be compiled to Dalvik bytecode. But obviously that would be a lot of work. I only mention Swift since there were rumors in the past that Google was considering fully supporting Swift on Android. Plus, to be clear, you can run Swift on Android now using the native SDK, just not on Dalvik for making GUI apps.
