These are not costs, since "people wondering" does not cost anybody anything. People are free to wonder about anything, it's not a cost on existing users on PHP. If those people are interested in learning something, they'd read the manual and know. If they don't, they can keep wondering, it's not an argument for anything. -- Stas Malyshev smalys...@gmail.com -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
