A superset of ... what the? Why do you keep trotting out this garbage thread after thread?

Every language takes influences from others, if that's what you meant. Scala is influenced by Java, C# and Haskell, in that order. Kotlin is influenced by Scala and Java, etc.

The "superset" and "Lisp, Haskell and Javascript in the same compiler" comments are unhinged from the reality of any language I recognise.
