> Great systems also have advice. There's no universally accepted name for this feature. Sometimes it's called hooks, or filters, or aspect-oriented programming. As far as I know, Lisp had it first, and it's called advice in Lisp. Advice is a mini-framework that provides before, around, and after hooks by which you can programmatically modify the behavior of some action or function call in the system. Not all advice systems are created equal. The more scope that is given to an advice system — that is, the more reach it has in the system it's advising — the more powerful the parent system will be.
