Which useful libraries for writing code on Kotlin do you know?

Hi!
An infrastructure for developing on Kotlin is growing up a really fast, and I suppose that there are many useful libraries that not everyone who writes code on Kotlin knows about.

Please share your experience!

For me:

1. kotlin-logging, logging in Kotlin style
2. Detekt, static code analysis
3. dokka, documentation generator
4. arrow, functional companion to Kotlin's Standard Library

Also:

1. KotlinPoet, API for generating .kt source files
2. Result, the modelling for success/failure of operations
