 Unless I am missing something really obvious here, this ticket makes a lot
 of sense to me.

 There have been many instances where I have wanted to optionally pass my
 own parameters to hook callback functions, that __haven't__ been specified
 in the hooks {{{do_actions()}}} function call.

 It would be hugely beneficial to also be able to pass in an array (say) as
 an extra parameter when using {{{add_action()}}}. Something like:

 {{{
 $extra_args = array( 'value1', 'value2', 'value3' );
 add_action( $hook, $callback, $priority, $accepted_args, $extra_args );
 }}}

 Then, in the callback function the {{{$extra_args}}} array would be
 accessible as well as any {{{$accepted_args}}} parameters. Maybe make it
 easy to access by always making it the last parameter?

 {{{
 function my_callback($wp1, $wp2, $args) {
     //$args[0] = 'value1';
     //$args[1] = 'value2';
     //$args[2] = 'value3';
 }
 $extra_args = array( 'value1', 'value2', 'value3' );
 add_action( 'some_hook', 'my_callback', 10, 2, $accepted_args, $extra_args
 );
 }}}

 Note: I know I can achieve the same thing using global vars, but I don't
 really want to define them unnecessarily when using a parameter would make
 more sense.
