I had the same thought about Lisp when I first saw this post, but after looking around a bit, I wasn't able to find any way to do this properly in Common Lisp. (This isn't to say that there's not one; just that it's not immediately obvious to me.) With macros one can specify a &whole parameter to grab the argument list, but that's not valid for functions. And for functions one can start off the argument list with a &rest parameter which will grab the entire list of arguments, but then you can only use &key and &aux parameters afterward, no normal or &optional ones.

Of course, this may be a limitation of Common Lisp only (or, as I said, maybe not; I may just be ignorant); I don't really know any other Lisps well enough to speculate.
