Feature Request: array declaration

Howdy, I hope this isn't too late in the game for PHP5, but I thought I'd throw out a request for a feature for array() declaration. I'd like to be able to be lazy and declare something like $foo = array('A' <=> 'Admin', 'C' <=> 'Customer'); which is really just a shortcut way to declare $foo = array('A' => 'Admin', 'Admin' => 'A',

                     'C' => 'Customer', 'Customer' => 'C');

Dunno if anyone else would find this usefull, but it'd be nice to have as a quick way to declare a simple lookup array. Walt
