Dump::out and late static binding

[fidian]

Dump::out() should not be hardcoded to make new Dump(...). It fails when I do something like this:

class Dump2 extends Dump {
    public function objectMyObject($what, $silent = false) {
        return $this->helperString('No Dumping MyObject', $silent);
    }
}

class MyObject {
    private $DoNotShowMe = 'Noooooooo';
}

$d = new MyObject();
Dump2::out($d);

Expected:

'No Dumping MyObject'

Actual:

MyObject::__set_state(array(
    'DoNotShowMe' => 'Noooooooo'
))
