Sounds very useful, and the only problem is that it will lose argument
order (not that I use it very often, but it might be good to have in some
cases).

   1   2         3     4    5           6               7       8

One solution could be to let each "data item" contain the argument's 
position, like this perhaps:

>     $args['']        array(array(1=>'123'), 
                             array(5=>'apple pie')
                             array(7=>'+plus'))
>     $args['list']    array(2=>'none')
>     $args['+']       array(array(3=>'list'),
                             array(8=>'something'))
>     $args['-']       array(array(4=>'any'))
>     $args['title']   array(6=>'my page')

Another solution could be to add an element to $args that contiain an 
ordered list of the parameters that is also categorized, e.g.

    $args['ordered-parameters'] = 
         array(array(''=>'123'),
               array('list'=>'none'),
               array('+'=>'list'),
               array('-'=>'any'),
               array(''=>'apple pie'),
               array('title'=>'my page'),
               array(''=>'+plus'),
               array('+'=>'something')
              )                       

I'm sure there are many other possibilites.
