If I have a function that takes a String and parses it to return some MyDataClass, is it idiomatic in Kotlin to return MyDataClass? which is null if the input String doesn't match the pattern? Or should I use a Result or throw an exception or something? In this case returning null would happen "normally" and would not be exceptional in any way

Great, thanks. I think my particular use case is definitely the last category.

A sealed class instead of an null maybe another option

You are right. It was "maybe"
Also I am starting with kotlin so my opinion is too weak. I came from Java where we love null (and nullPointerException) 🤪
