Description:
------------
"return ($val);" does not work in a function that returns a reference. "return $val;" is OK.

Reproduce code:
---------------
class lala
{
	var $val;
	
	function lala ()
	{
		$this->val = 0;
	}
	
	function &get_val ()
	{
		$inf = 88;
		$this->val = $inf;
		return ($inf);
	}
}

$obj = new lala;
$vvv = &$obj->get_val ();


Actual result:
--------------
Fatal error: Only variables or references can be returned by reference in /usr/local/apache/site/htdocs/bug.php on line 15

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Yup, this is expected.

http://pt.php.net/return

statement: "Note:  Note that since return() (...), the parentheses surrounding its arguments are not required (...) it doesn't matter one way or the other."

in example above, return ($val) or return $val seems to matter.
