Object Creation

+SomeObject :: new(?NewObject)

NewObject is created with SomeObject as super. NewObject could be an atom, variable, or compound term whose arguments are distinct variables.

+SomeObject :: new(?NewObject,+Supers)

NewObject is created with Supers specifying the super objects (prototypes). Supers is a list containing super specifications. A super specification is either an object identifier or a pair Object-NotInheritList where NotInheritList specifies methods not to inherit from Object. NewObject could be an atom, variable, or compound term whose arguments are distinct variables.

The object vehicle is created having the proto-object object as super, followed by creating moving_van with vehicle as super, followed by creating truck.
