According to the language reference, there are no requirement for classes to subclass any standard root class, so can I Nclude or omit a superclass as needed.

Note that omitting a superclass from the class declaration, doesn ' t assign a implicit base superclass of any kind. It defines a base class, which would effectively become the root for an independent class hierarchy.

Trying to reference from super a class without a super class (i.e. a base class) would result in a compile time error

‘super‘ members cannot be referenced in a root class
