Still doesn't take care of the private stuff..

Well, I'm not asking you to implement this right away, am I :) I might come across impatient, but I just like messing with zend/php and hope someday code will of mine will be added to Zend/php haha:))) > In the long run, I think we will make changes similar to public/private but I > don't think I personally will advocate the slow-down/increase memory way.
