Properties of the oof.fs model

• This model combines object oriented programming with information hiding. It helps you writing large application, where scoping is necessary, because it provides class-oriented scoping.
• Named objects, object pointers, and object arrays can be created, selector invocation uses the "object selector" syntax. Selector invocation to objects and/or selectors on the stack is a bit less convenient, but possible.
• Selector invocation and instance variable usage of the active object is straightforward, since both make use of the active object.
• Late binding is efficient and easy to use.
• State-smart objects parse selectors. However, extensibility is provided using a (parsing) selector postpone and a selector '.
• An implementation in ANS Forth is available.
