From manual page: http://www.php.net/functions.anonymous

Syntax for mixing `use` Closure clause with return type declaration doesn't seem to be documented anywhere.  It's then unclear whether the `use` clause should come before (where PHP7 actually wants it) or after (where HHVM wants it) the return type hint.

PHP7:
    $closure = function (string $str) use (&$something) : int {}

HHVM:
    $closure = function (string $str) : int use (&$something) {}

As this not only isn't obvious, but also is inconsistent with what HHVM supports for some time, it seems very useful to me to document this clearly.

Test script:
---------------
<?php

$something = 42;
$closure = function (string $str) use (&$something) : int {
	return strlen($str) + $something;
};
