It doesn't, really. CLOS methods are overloadable functions basically, i.e. 
you can define multiple methods of the same name, but with different argument 
types, and it'll pick the right one to call depending on the type(s) of the 
object(s) you pass as arguments. There's no concept of a receiver though.

Well, since we're discussing CLOS in the context of comparing it to ruby, it's 
still kinda on-topic, so unless someone complains, I see no reason not to 
continue this discussion here on the list.

HTH,
Sebastian
