• Note in particular the correspondence between Smalltalk's implicit metaclasses and Ruby's eigenclasses of classes.
• a metaobject protocol - a special form of meta-circular evaluator for object-oriented programming, in which the object system implements itself recursively via a system of metaclasses and metaobjects, which are themselves classes and objects.
• By contrast, in ObjVlisp, it is possible to define named metaclasses, and when defining a class one must specify which named metaclass it will instantiate.
• Support for OOP concepts such as classes, object, methods, encapsulation, messaging, polymorphism, inheritance and multiple inheritance (metaclasses and mix-in classes).
• This enables knowledge about instances of those metaclasses to be inferred by semantic reasoners using statements made in the metaclass.
