Description:
------------
aggrgate() does not aggregate the method that has the name similar to the name of the constructor...?

Reproduce code:
---------------
<?php

class a {
	function a() {
	    echo "CREATED A;";
	}

}
class b {
	function bb() {
	    echo "BB();";
	}

	function xbb() {
	    echo "XBB();";
	}
}

$a=new a();
aggregate($a, "b");
$a->xbb();
$a->bb();

?>


Expected result:
----------------
CREATED A;XBB();BB();

Actual result:
--------------
CREATED A;XBB()

Fatal error: Call to undefined function: bb() in test.php on line 28
