Description:
------------
It is possible to access values (and names to an extent) of all object properties regardless their access level using reset/end/each.

This behavior also prevents the expected behavior from using reset/next/current with clasess implementing Iterator/ArrayAccess interfaces.

Test script:
---------------
<?php

class MyClass
{
  private $var1 = 'Some value 1';
  protected $var2 = 'Some value 2';
  protected $var3 = 'Some value 3';
}

$obj = new MyClass;
foreach($obj as $key => $value)
{
  print "$key => $value\n";
}
reset($obj);
while($val = each($obj)) print_r($val);


Expected result:
----------------
No output.

Actual result:
--------------
The class content is dumped from second loop.
