Can you clarify? I'm not sure what performance improvement trick you are referring to, or what you mean by "importing all functions". Are you saying it's a misconception that triggering an autoloader on unqualified function calls in a namespace will slow down performance? As I understand it, this is the roadblock for function autoloading. Best regards, Theodore -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
