toString() and Object #ID

Just as a side note, this broke a few things for me. For example, in an application, I have 2 arrays of objects, and I try to call array_diff() on them. Before PHP 5.2, it would work, possibly because array_diff() would cast the objects as strings, and then compare them (if I understood the problem correctly). Now, this doesn't work anymore, because the object can't be cast to string by default. Of course, I could add a __toString() method to the objects and return something there, but problem is, all objects are extended from a base class from PEAR (it's DB_DataObject), and it wouldn't be a Good Thing to modify the PEAR class directly (updates would break). So, I got kind of stuck, and tried to add the __toString() dynamically to the objects in question using the "runkit" PECL package, but although it adds the method correctly, PHP doesn't recognize it as a magic method, and won't call it when needed (filed bug #11691 on PECL for it). Do you think there's an easy and clean approaching to solve this kind of problem? Or maybe the problem should be solved on array_diff() and other functions to make them not try to cast the object as a string to compare?
