PHP_5_3 as of this morning does not contain that patch that makes ArrayObject behave like an array (reset()).
Here's a test for that (I don't have php-src karma) if anyone would care to commit it. Passes on 5.2.6, but fails on 5.3alpha3-dev

<?php
$a = new ArrayObject;
$a['foo'] = 'bar';
echo reset($a);
echo count($a);
echo current($a);
