creating a belongs_to association to a model's same class doesn't work

[jcs]

a class that has a belongs_to relationship to the same class can't be defined without causing an infinite regression until php runs out of memory.

with a sql schema of

create table posts (id int, parent_post_id int)

and a Post.php of

class Post extends ActiveRecord\Model {
    static $belongs_to = array(
         array("parent_post", "class_name" => "Post")
    );
}

it will regress infinitely when trying to load the model.
