What else besides array access, counting and traversing is possible that may differ from classes that implement those interfaces? > A general "intersection type" system might be more useful, because then you > could require the parts you specifically needed, such as > "traversable&ArrayAccess" or "traversable&countable". I think that's too complicated and we should make it as easy as possible for PHP developers. Also, there's already an RFC for intersection types but it was never adopted: https://wiki.php.net/rfc/intersection_types -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
