How to find if a callback is a specific method?

At one point I have:

$callback = array(&$this, 'foo');

How can I find out later if $callback is the foo method?

if($callback == array(&$this, 'foo')) doesn't seem to work

<?php
class A
{
    public function Test1()
    {
        $callback = array(&$this, 'foo');
        var_dump($callback == array(&$this, 'foo'));
    }

    public function foo()
    {
    }   
}

$a = new A();
$a->Test1();
?>

Callbacks are just simple arrays, and the method name is a string. Just check the second element of the array:

if ($callback[1] == 'foo')
