Scala, as I recall. It encourages using Options (Some/None), but since it runs on the JVM and will often interop with Java libraries, you can also have nulls.

Oh no! Does it not have a type for NonNull references, like Rust does?

  Since Scala 3, it can have total static analysis where nulls become a separate type that has to be explicitly declared in type signatures. So, yes.
