fun <T> Option<T>.getOrNull(): T?

fun <T> Optional<T>.getOrNull(): T?

Converts Optional to Kotlin nullable.

fun <S> GroupState<S>.getOrNull(): S?

(Kotlin-specific) Returns the group state value if it exists, else null. This is comparable to GroupState.getOption, but instead utilises Kotlin's nullability features to get the same result.
