URL can take 0, 1, 2, or 3 un-named argument:
URL(args=[],vars={})
URL(function,args=[],vars={})
URL(controller, function,args=[],vars={})
URL(application, controller, function,args=[],vars={})
args and vars and also optional but, if you pass values for them, they
must be named.
You should not specify application, controller and/or function if they
are the same as the current ones.
