Does it mean you preload every script you could use ? In a typical application with potential access to, say, 4,000/5,000 PHP scripts, does it mean you will preload them all before running anything ? I hope it is not the case because it's generally impossible to know in advance which files you'll need. That's even the main benfit of autoloading. An idea I had during a previous thread about script inclusion is a way to register a list of patterns that paths should match. The main script would register them and, then, every include/require would be filtered through the list. It just requires to run realpath() and match the result against a set of patterns. Don't know the performance impact. Just an idea. Regards François
