I agree with Kiffin.  Ideally there would be an appendix with some of  
the more relevant ways of dealing with things listed in there.

One of the problems with mod_perl is that its sufficiently big and  
complex enough that it's not trivial to have a spare mod_perl server  
lying around.  Maybe someone who has one anyway can confirm this

You can only have varying URL Args for things at the end of the chain,  
kind of by definition, so this is the :Args [nothing] use case.  Then  
you'd need to check length  of the $c->req->args array ref manually in  
your controller if you only wanted a certain range of trailing args.
