Anonymous Function return value

Update: Starting with PHP7, it is now possible to use anonymous function dereferencing using the syntax: ``` $array[] = [ 'new' => (function() { ... return mt_rand(); })(), 'or' => getClosure()() ] ``` Original post: I've recently experimenting with some things, and wondered if there was any way to use the return value of an anonymous function Lets say I had a for-loop that made an array that each value of the array had to have a database call, something I would like to do is: ``` for($i = 0; $i != 10; $i++) { $array[] = [ 'new' => function(){ // some proccesing here maybe // lets use mt_rand for this example. return mt_rand(); }, 'old' => function(){ return mt_rand(); } ]; } ``` or maybe ``` echo function(){ // again, we'll just use mt_rand return mt_rand(); }; ``` These both return a `closure` class. Is there anyway to actually pass the return value of them back to the array or echo, for the examples above? Update: I've established this isn't possible so, feature request can be found here: http://bugs.php.net/bug.php?id=64608
