---------------------------------------------------------------

Coincidentally, I had to learn Kotlin for a gig I just had starting last December, so nowadays I'm a bit more comfortable with the language and can provide feedback. One thing I'd suggest based on a different Kotlin logging framework I tried out is perhaps offering a way to inject the logger into the companion object. For example:

{code}
class Foo {
  companion object : Logging

  fun foo() {
    logger.info("Hello, $world")
  }
}
{code}

What's neat is this would be vaguely similar to how the Scala API works as a mixin. You can define a val with an initial value in an interface AFAIK, so you could offer said Logging mixin for either the class itself or the companion object (though via the companion object, we may need custom code to get the correct class name for the logger).

> Similar to LOG4J2-1181 for Scala, provide a Kotlin wrapper for the Log4j 2 API that makes use of Kotlin features like delegates and string interpolation.
> If there is interest in this, I'd like to contribute a patch.
