I agree, if you want to document that you code accepts mixed types you could simple write /* mixed */, i.e. a comment. If you're talking about tool support then the tool could also support this comment. Would not be unheard of either. - Chris -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
