It's something I'd definitely like to see, and is perhaps something the long-awaited PHP 6 could have. One of PHP's big problems is the fact that there is no real specification whatsoever, only the single Zend implementation. Of course, this presents a problem in specifying PHP's behaviour, as the result would likely be "do exactly what the Zend engine does". Perhaps we'd discover things in Zend which don't work the way they're supposed to, mind. -- Andrea Faulds http://ajf.me/
