Well, that was exactly my point, though not expressed explicitly: if you can put null there, you don't need 'nullable'. If you say 'MyClass $a', it doesn't allow null, if you say 'MyClass $a = null', it allows null. Or, other way around, if you say 'nullable MyClass $a', it defaults to null, otherwise it has no default. I think we should prohibit to put any default to typehinted variables except null in any case - since it doesn't make any sense except promoting code based on is_object checks etc. - the exact thing we wanted to avoid with typehints. -- Stanislav Malyshev, Zend Products Engineer [EMAIL PROTECTED] http://www.zend.com/ +972-3-6139665 ext.115 -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
