Why? This doesn't seem right. If we are in the case of HandledArgumentViolation we want to exit the process with the correct exitCode. Right?
I imagine that this is because of the exhaustive enums. But I think that instead of else that doesn't give any information about which other cases go there we could use: null -> Unit or null -> { /* no-op */ }. I prefer the first one because with the second I always have a bad time: Does this case do nothing or does it return a lambda that does nothing?

Good catch. This is indeed a miss from my side about the behavioral change.

I imagine that you are adding this ? to match what org.jetbrains.kotlin.utils.addToStdlib.safeAs did, right? If it's that I'm fine. But I think that an extension function that when receives null always return null shouldn't handle that case. That responsability should be handled by the caller.

@BraisGabin thanks for your feedback, I've raised #4143 to address it. |
