patterns in SPL and PEAR

Hi, since both ext/SPL and PEAR are increasingly making classes available with the sole purpose of exposing OO design patterns I would like to make sure that both sides know this and that we try and remain compatible as much as possible. Especially in things like method naming. ext/SPL Observer: http://www.php.net/~helly/php/ext/spl/interfaceObserver.html ext/SPL Subject: http://www.php.net/~helly/php/ext/spl/interfaceSubject.html PEAR::Event_Dispatcher: http://pear.php.net/package/Event_Dispatcher PEAR::PEAR_Delegator: http://pear.php.net/package/PEAR_Delegator regards, Lukas
