A modern programming language that makes developers happier.

kotlinlang

An interesting idea. Do you think there are many cases where `Nothing?` is used and where `Null` would be more expressive?

It's interesting to consider what is primary and what is derivative. E.g. `Null` can be a typealias to `Nothing?`, and `Nothing?` can be considered as a union of `Nothing | Null`

Though at this point, introducing `Null` identifier in a package imported by default would be rather disturbing. There can be objects named `Null` (<https://github.com/pact-foundation/pact-jvm/blob/7cd4ff4d3be7f8e4a3534ae67c3ef18d0b998dc8/core/support/src/main/kotlin/au/com/dius/pact/core/support/json/JsonValue.kt#L41>) and they can lead to a conflict or confusion when being in scope with the `Null` typealias.
