Do you feel that a language has to have something at the language level to prevent NPEs?

In my experience, Scala does pretty well without it.

I guess is your point that the language should make it impossible to write bad code, not just make it easy to write good code?

Just a heads up, Scala 3 actually has a compile flag that will make types exclude ‘null’ as a valid subtype, so every nullable variable will have to have type signatures like String | Null.
