On a related note, you might also want to take a look at CLOS (the Common Lisp Object System) where it talks about method selection. They've got a pretty clear and general model that describes every imaginable (and unimaginable) thing you'd want to do with dispatch. It's broken into 3 steps, any one of which you can customize: - find all applicable methods - sort them in order of specificity - apply some kind of combining operation to this list (e.g. select 1st) Granted, this is hardly efficient, and from what I've seen you need to be careful in how you use MMD to get decent performance in Lisp. But it's still helpful in laying out the design space. /s
