Description:
------------
When using object overloading I thought I might receive at the very least a warning error if I attempted to declare any of the magic methods as private in a class definition as per the documentation:

"All overloading methods must be defined as public."

http://php.net/language.oop5.overloading.php

Also tested in PHP 6CVS-2008-04-17 (snap)

Reproduce code:
---------------
class MemberTest {
    /**  Location for overloaded data.  */
    private $data = array();
    private function __set($name, $value) {
        echo "Setting '$name' to '$value'\n";
        $this->data[$name] = $value;
    }
    private function __get($name) {
        echo "Getting '$name'\n";
        if (array_key_exists($name, $this->data)) {
            return $this->data[$name];
        }
    }
}
echo "<pre>\n";
$obj = new MemberTest;
$obj->a = 1;
echo $obj->a . "\n";
exit;

Expected result:
----------------
A FATAL error or at the very least a WARNING error with
    error_reporting  =  E_ALL | E_STRICT

Actual result:
--------------
<pre>
Setting 'a' to '1'
Getting 'a'
