A modern programming language that makes developers happier.

kotlinlang

```
afterEvaluate {
		kotlin.sourceSets.all {
			languageSettings {
				enableLanguageFeature('InlineClasses')
				useExperimentalAnnotation('kotlin.ExperimentalUnsignedTypes')
			}
		}
	}
```
I have this in my root project `build.gradle` file inside a `subprojects` block. When I convert the file to kotlin dsl, I get "sourceSets could not be resolved". Not sure how to covert that bit from groovy to kotlin.

Currently using `(property("kotlin") as KotlinMultiplatformExtension)` as work-around.
