C.1.3 Forward Chaining and the Backward Chainer

For more uniform semantics throughout KnowledgeWorks, the right hand side of KnowledgeWorks forward chaining rules are executed directly by the backward chainer, as is the default meta-interpreter for a context which has no meta-interpreter specially defined. When compiled with debugging turned off, in many cases the backward chainer can be optimized out leaving raw Lisp code.
