Meant for boolean NOR operations. You don't need to override this operator. Just override and, or, and not. The compiler will automatically create a matching version of the nor operator for you. In order for nor to be generated, the parameter types and return type for and and or must match each other. Furthermore, the parameter and return type of not must match those declared by and and or. The compiler will then copy those parameter and return types to the new nor override.
operator nor var /TypeDescriptor1/ left, var /TypeDescriptor2/ right returns boolean
operator nor var boolean bLeft, var boolean bRight returns boolean
