Experimental

@Retention(value = AnnotationRetention.BINARY)
@Target(allowedTargets = [AnnotationTarget.ANNOTATION_CLASS])
annotation Experimental

Denotes that the annotated element is a marker of an experimental API.

Any declaration annotated with this marker is considered part of an unstable API surface and its call sites should accept the experimental aspect of it either by using UseExperimental, or by being annotated with that marker themselves, effectively causing further propagation of that experimental aspect.
