I wish Kotlin wasn't effectively a single IDE language. I tried the eclipse plugin but it was only barely usable. For this reason I currently prefer Scala and Groovy but both of those have their own drawbacks. I do probably like the language syntax of Kotlin most of all (though lacking array and map literals is a huge pain). I wish someone would rewrite Groovy with static typing / type checking being the default and the Kotlin syntax for expressing nullable / non-nullable type declarations.
