I believe it's been discussed a few times but I think it's highly unlikely due to the way the engine works. As I said in my reply to shiplu, class constants and member variables are defined not evaluated, so making expressions possible is a fairly major modification for, what I see as fairly minimal benefit. There's definitely an argument to be made that a class definition should not contain anything that needs to be evaluated. I certainly see it as breaking the basics of object oriented design. > It just made me wonder if I was doing something wrong. Technically you were, but nobody died so it's ok :) -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
