http://en.wikipedia.org/wiki/Multiple_dispatch#Common_Lisp http://en.wikipedia.org/wiki/Multiple_dispatch#Common_Lisp I tend to prefer the (defmethod) form in CL. You get generic functions which can retrieve the function object specialized for the parameters with (find-method). You also get the auxiliary method goodness... But the great thing with Python that the article shows is that there's probably a way you can get those things in Python too if you needed them. So does Python have multiple dispatch or can you just implement it?

The challenge with expressive features like multimethods - does your language give you the tools not only to implement it, but to make it fast? This is yet another benefit of macros - the ability to add features like this and get good, perhaps even great, performance.
