Description:

similar to bug request 31554, http://bugs.php.net/bug.php?id=31554

can const be modified to be assigned output from an expression, similar to the define() function?


Reproduce code:
---------------
define( 'TEST1', 3+3); //works
class devil {
    const TEST2 = 3+3; //parse error unexpected '+'
    const TEST3 = (3+3); //parse error unexpected '('
    public function __construct() {
        echo TEST1;
        echo self::TEST2;
        echo self::TEST3;
    }
}
$obFoo = new devil();

Expected result:
----------------
666

Actual result:
--------------
Parse error: parse error, unexpected '+', expecting ',' or ';'
