Run another controller's method

[eluser]Sam Dark[/eluser]
redirect() from URL Helper? It just redirects with http headers or meta.

I need to reroute application flow, not to redirect!

Code:

class A extends Controller {
  function index($id, $name){
    $param['id'] = $id;
    $param['name'] = $name;
    $this->delegate('b', 'say_it', $param);
  }
}

class B extends Controller {
  function say_it($id, $name){
    print 'Hello, '.$name.'! Your id is '.$id.'.';
    $this->delegate('c', 'doit');
  }
}

class C extends Controller {
  function doit(){
    print 'done';
  }
}
