Basically, when you get to a specific point where you need to make a decision, you raise a signal and "something" above you in the call stack can make the decision of whether to proceed or abort -- without unwinding the call stack. You could certainly do it trivially in Lisp with @:before@ functions. Actually this would work totally differently.

That is, you can monkey-patch any function to be generic, then specialize it with functions that provide security constraints (and call next_method). Anyway, I think that's kind of what you are talking about here. Just, you know, if you wanted to make it more relevent, I think PEAK’s generic functions might provide the same thing.
