A modern programming language that makes developers happier.

kotlinlang

I'm trying to get started with kotlin but when attempting to write small composable functions (as I would write in Clojure/Lisp, Javascript, Ocaml, (maybe) Golang) I quickly get into some hairy (and seemingly unresolvable) generics mess remniscient of my worst days with Java.

Are there any nice tutorials which gives a succinct overview of Kotlin wrt. generics and how to best navigate it ? Granted, the Kafka API is particularly wierd (You give two serializer classes and get a corresponding producer - magically they map StringSerializer=&gt;String, LongSerializer=&gt;Long etc) - but it seems hard to work with
