Hi Chris! I really like this proposal. `compact` is cumbersome to use, or lets say, almost impossible without an intelligent IDE. However, what is more important is the fact that is would allow for a very readable and usable approach for destructuring of associative arrays (as illustrated by your example) which is very, very neat. The change is also extremely minimal which speaks for it. I would support you in writing up an RFC for this (if desired). -- Richard "Fleshgrinder" Fussenegger -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
