I think it should cast to a string if possible. You are now making iterator_to_array not work with the new feature, and I find that a bit silly. Whether it should be __toString (or __toKey) I don't really care, but this new support for objects should be supported everywhere (and that includes iterator_to_array). cheers, Derick -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
