[Q]How to get instance of the Invoking Controller

[eluser]m4rw3r[/eluser]
get_instance() returns the instance of the first (usually the only) loaded controller.

Example:

Code:

class Foo extends Controller{
    var $bar = 'Foo';
    function index(){
        echo $this->bar;

        $CI =& get_instance();
        $CI->bar = 'bar';

        echo $this->bar;
    }
}

This should echo Foobar if I didn't mess up somewhere.
