I'm no expert and I want to make a valid contribution here. In trying to understand the proposal of allowing properties via interfaces from your (Chris') point of view, what benefit do we get? Allowing unset on properties in the class or in the interface, then this seems like normal class properties. We are talking about extending the behaviour of interfaces. Surely this implies a greater amount of rigidity? -- ----- Richard Quadling Zend Certified Engineer : http://zend.com/zce.php?c=ZEND002498&r=213474731 "Standing on the shoulders of some very clever giants!" -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
