ExperimentalTypeInference

The experimental marker for type inference augmenting annotations.

Any usage of a declaration annotated with @ExperimentalTypeInference must be accepted either by annotating that usage with the OptIn annotation, e.g. @OptIn(ExperimentalTypeInference::class), or by using the compiler argument -opt-in=kotlin.experimental.ExperimentalTypeInference.
