    The opposite of:

      ClassTail : ClassHeritageopt { ClassBody }

      It is a Syntax Error if ClassHeritage is not present and the following algorithm evaluates to true:
        1. Let constructor be ConstructorMethod of ClassBody.
        2. If constructor is empty, return false.
        3. Return HasDirectSuper of constructor.
