Are there plans to allow anonymous functions as callbacks?

Hi. Quite a simple question (assuming I've got the terminology correct). Are there any plans to allow code like this (amended example taken from the array_map() documentation) ... <?php $a = array(1, 2, 3, 4, 5); $b = array_map(function($n){return($n * $n * $n)}, $a); print_r($b); For me, this is cleaner than having a use-once, namespace-polluting function. Currently, this is producing a parse error. A real alternative though would be to allow nested functions... <?php function cube_array($a) { function cube($n) { return($n * $n * $n); } return array_map("cube", $a); } $a = array(1, 2, 3, 4, 5); $b = cube_array($a); print_r($b); Ideally, cube() would not be visible outside of cube_array(). Scoped functions.
