I have always liked the idea of having protocols say more than just "these are the functions and these are the arguments, which are optional, ane maybe what their types are.
You can have that in Lisp to a point with Interface-Passing Style: http://fare.livejournal.com/155094.html
I have (ab)used this style of late as it meshes with my habit of defining protocols that are less designed than evolved. I'll have a moment of realization that a group of generic functions describe a theme which may be varied, and I'll end up with an abstract interface, some mixins, and a defining macro for subtypes. So far type hierarchies have been shallow, but I'm willing to see how far design-by-refactoring takes me.
