The real problem here is that the chances of PHP 5.3 being used in production anytime soon are rather slim. "Stable" distros, like Debian, Red Hat and CentOS, are still using PHP 5.1, which has long since been found to have issues that have been fixed and improved in PHP 5.2. Some hosts are still not even up to that level...<p>For open-source projects like what I'm working on, our need to support a wide variety of hosting environments means that we took flack even just dropping compatibility for PHP 4 and 5.0.<p>I would love to be able to start using some of the newer/better features arriving in 5.3, but sadly, PHP 6.1 will likely be out before I can ever start using those features in public projects... :(
