Some of the things I like about Kotlin are idioms such as

for ((k, v) in map) {
    println("$k -> $v")
}

I have wanted to do things this easily in Scala for a long time, but I tire of the explanations from some people as to why I am a stupid idiot for expecting that. I really appreciate that in Kotlin, it just works, it's readable, and easy to remember. Granted it's still incomplete, but things are improving in a direction I like.
