Consider what happens to a rule method at runtime. As a method is executed, rules are posted in preparation for processing by the inference engine. The posted rules are not executed until a backwardchain or forwardchain keyword is reached. This temporal separation in the execution of rule methods and their rules has several important implications for programming in Aion.
Keep in mind these two distinct "times" to understand how rules behave. Posting time is when the method is executed and the rules posted. Chaining time is when the inference engine executes the rules.
