Description:
------------
Is this a bug?

If I try to access a private attribute with a list function
I can see them without problems.
If I try to access them directly I receive a fatal error.


Reproduce code:
---------------
<?php
class Dog{
private $name;
private $legs;

public function __construct(){
$this->legs = 4;
}
}

//this displays all my attributes
$aDog = new Dog();
while (list($key, $val) = each($aDog)) {
echo "$key => $val<br>";
}

//this displays a fatar error
echo $aDog->name;

?>

Expected result:
----------------
I expect a fatal error in both cases

Actual result:
--------------
I can see all my private attributes with the list function.
But a fatal error with I access them directly.
