The 'functor' facility is for generic programming. 
documented? The page on modules in the manual makes no explicit association between interfaces and functors. Indeed, I don't see any hint that interfaces can be used in functor definitions the way you do in your egg.


Buried at the bottom.

Oh, okay, I see it now. I had skimmed the functors section, but missed the sentence referring to DEFINE-INTERFACE.  I still think the doc could stand to be clarified a bit--e.g., with a specific example of using an interface in a functor definition. I would imagine many people are unfamiliar with functors, especially those who have not programmed in other functional languages. Though the part about interfaces is a fairly minor detail, sometimes confusion about the little things can get in the way of understanding the important concepts.
