This annotation marks the experimental kotlin-reflect API that allows to approximate a Kotlin lambda or a function expression instance to a KFunction instance. The behavior of this API may be changed or the API may be removed completely in any further release.

Any usage of a declaration annotated with @ExperimentalReflectionOnLambdas should be accepted either by annotating that usage with the OptIn annotation, e.g. @OptIn(ExperimentalReflectionOnLambdas::class), or by using the compiler argument -Xopt-in=kotlin.reflect.jvm.ExperimentalReflectionOnLambdas.
