Not really needed now that PHP 5.4 has it by default (though in reality it'll be a while before 5.4 is default), but I'd use it if it let me do the following: $foo = MyFunction()[2]; It's the one feature in PHP 5.4 that made me genuinely happy. Another thing I'd love is a doctype of sorts for PHP. So I could go: <?php uses "5.1.2"; .... and then the PHP engine will treat itself as if it is PHP 5.1.2 or whatever. Yeah, not going to happen ever, but it'd be nice.
