Description:
------------
I would be nice if PHP 6.x can use operator [] with called function.


Reproduce code:
---------------
<?
 function f(){
  return(array('a','b'));
 }

 print(f()[0]);
?>


Expected result:
----------------
Like now:

<?
 function f(){
  return(array('a','b'));
 }

 $f=f();
 print($f[0]);
 unset($f);
?>

Actual result:
--------------
Parse error: syntax error, unexpected '['
