Hi Darby,
Finally, I would recommend that Zend_Loader be eschewed, in favor of using require_once, whenever possible. If there are any framework components using Zend_Loader, where require_once would work nicely instead, please let us know about it.
Based on that recommendation, is it correct then to presume that it would be wise to also avoid using Zend_Loader::registerAutoload() for the same performance reasons?
