For what it is worth, I would find this functionality EXTREMELY useful. The classes I create ARE used by other developers both within my organisation and outside and as I'm currently porting GUI apps from Delphi to web apps using PHP and missing things like type hinting of scalars AND overloaded function defs is a pain as I now have 1 method with a header which has to parse the parameter types to determine what is required to be called. I think this is a GREAT feature. Even if it was JUST for E_STRICT OOP code. -- ----- Richard Quadling Zend Certified Engineer : http://zend.com/zce.php?c=ZEND002498&r=213474731 "Standing on the shoulders of some very clever giants!"
