Description:
------------
If i have an overloaded __set function in a class and call parent::__set from another function, the parent calls the child's __set back and a loop gets created like this:

parent::__set (initial call)
child::_set
parent::_set

I need __set function to do some prefixing by default when assigning new string properties by default, i need a custom function to assign un-prefixed properties too, if there is a need (will happen very rarely)... I need this to auto prefix string variables passed to my view object (they gotta be passed as object properties), the MVC framework is a 3rd party framework, i'm extending it's view object and i don't want to modify the original source...

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

class A
{
	public function __set($pKey, $pValue)
	{
		echo("Class: ".get_class()."| Passed Value:".$pValue."<BR>");
		$this->$pKey = $pValue;
		return true;
	}
}

class B extends A
{
	function setRaw($pKey, $pValue)
	{
		parent::__set($pKey, $pValue);
	}

	function __set($pKey, $pValue)
	{
		echo("Class: ".get_class()."| Passed Value:".$pValue."<BR>");
		$pValue = $this->prefix($pValue);
		parent::__set($pKey, $pValue);
	}

	function prefix($pValue)
	{
		if(is_string($pValue))
		{
			return "(prefixed) ".$pValue;
		}
		return $pValue;
	}
}

$b = new B();

echo("Calling: setRaw()<br>");
$b->setRaw("raw", "shouldn't be prefixed");
echo("<br>");

echo("Calling: __set()<br>");
$b->prefixed = "should be prefixed";

echo("<br>Variable after setraw: ".$b->raw);
echo("<br>Variable after set: ".$b->prefixed);
echo("<br>");

?>

Expected result:
----------------
Calling: setRaw()
Class: A| Passed Value:shouldn't be prefixed

Calling: __set()
Class: B| Passed Value:should be prefixed
Class: A| Passed Value:(prefixed) should be prefixed

Variable after setRaw: shouldn't be prefixed
Variable after set: (prefixed) should be prefixed


Actual result:
--------------
Calling: setRaw()
Class: A| Passed Value:shouldn't be prefixed
Class: B| Passed Value:shouldn't be prefixed
Class: A| Passed Value:(prefixed) shouldn't be prefixed

Calling: __set()
Class: B| Passed Value:should be prefixed
Class: A| Passed Value:(prefixed) should be prefixed

Variable after setraw: (prefixed) shouldn't be prefixed
Variable after set: (prefixed) should be prefixed
