suspend fun <B : Any> OptionEffect<*>.ensureNotNull(value: B?): B

Ensures that value is not null. When the value is not null, then it will be returned as non null and the check value is now smart-checked to non-null. Otherwise, if the value is null then the option binding will short-circuit with None.
