Not familiar with Kotlin but how does that work? Does it come included with a PAL? Because it you want to be platform agnostic, you can't for instance use a Java RegularExpression in your platform agnostic code.

The PAL (Platform Abstraction Layer I assume) is just the stdlib that is provided. The stdlib is not the same for all platforms, as can be seen in the documentation. A regex implementation is provided for all platforms, but is not quite the same on all platforms: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin.text/-r...

In shared code you can define interfaces that have to be implemented by any platform you use.
