This is the correct choice, IMO.  I think the spec should be explicit, 
however, that these values should be usable with * and ** (or apply()), as 
that will help clarify the meaning/rationale of the values.

I still think it should be url_args rather than url_vars -- I don't see any 
reason why they could be considered "variables" rather than 
arguments.  :)  But other than that, and the desire to see clarification 
about */** as an intended/supported use case, I give it a +1.
