The problem isn't null/nil as such, it's when the type system treats null values as legal at compile-time. But if you look at e.g. Kotlin, or C# with "#nullable enable", it tracks whether a given reference can be null or not. So you write if-else code instead of match, but you have to do that in order to actually do something with a reference. |
