It _has_ to be a language construct, and not a function (otherwise, we'd get a notice when first using the variable). It could, however, be a language construct that LOOKS like a function. This is how isset() and empty() work. Also, if this was possible as a function, it could be solved in user-space, and we wouldn't be having this conversation. (not that I claim to be an internals expert.. if I'm wrong, feel free to correct me) To pitch in my 0.02 CAD: this functionality is valuable to me, but I don't care what we name it, or how it works. I could also live without it: isset() + ternary + redundant typing. S -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
