Is there any way to report unknown keys in JSON deserialization? I don’t want to fail on unknown keys, but I don’t want to completely ignore them either. I could try a strict parse first, and then retry with { ignoreUnknownKeys = true } if that fails, but if there’s a cleaner way I would be happy to hear about it.
