what happens if I use this code.

class Foo {

    public $bar;

    public function __construct() {

       $this->bar = array($this, 'baz');
       $this->bar();
    }

    public function bar() {
       echo 'bar';
    }

    public function baz() {
       echo 'baz';
    }
}

new Foo();

What is the output of this snippet?

Are there the same rules as for closures?
