I first stumbled upon this problem in one of the RCs for PHP 5, but at the time I thought I was at fault...
Consider the documentation at http://www.php.net/manual/en/language.oop5.object-comparison.php : the documentation is a little vague, but it does say "Two object instances are equal if they have the same attributes and values, and are instances of the same class." Thus explaining the recursive loop... Maybe write a big flashing note in the documentation instead about this trap?
