Support for multiplatform programming is one of Kotlin’s key benefits. It reduces time spent writing and maintaining the same code for [different platforms](https://kotlinlang.org/docs/reference/mpp-supported-platforms.html) while retaining the flexibility and benefits of native programming.

 * [Kotlin Multiplatform Mobile](https://kotlinlang.org/lp/mobile/) for sharing code between Android and iOS

 *
 * ```
 * class Outer {
 *     inner class Inner
 * }
 *
 * fun foo() {
 *     val outer = Outer()
 *     outer.Inner()
 * }
 * ```
 *
 * While Kotlin always expects a constructor call when accessing `outer.Inner`, it nonetheless requires inner classes to be contained in
 * non-static scopes.
