Bug description:allow use( $var as $varCopy, &$var as $varRef) syntax for closures

Description:
------------
I'd like to propose a syntax for closures that would allow to specify a
name for 
the imported symbol (variable). Please see test script.

Test script:
---------------
$someLongArray =array( 1, 2, 3 );

$myFn =function() use( $someLongArray as $arrCopy, &$someLongArray as
$arrRef ) {
  array_push( $arrCopy, 4);
  array_push( $arrRef, 5);
};

print_r( $someLongArray);// 1, 2, 3, 5

Expected result:
----------------
Expecting such syntax to be supported in the future.

Actual result:
--------------
Syntax error.
