Description:
------------
When implementing the ArrayAccess Interface one could be tempted to think that
if "$obj[3] = $x" works, the common syntax "$obj[] = $x" would work as well.
But it doesn't. For this to work one has to enhance the offsetSet() method.

As it's only a one-liner I propose to put it into the example code on
http://de2.php.net/manual/en/class.arrayaccess.php

Expected result:
----------------
    public function offsetSet($offset, $value) {
        if ($offset == "") 
          $this->container[] = $value;
        else
          $this->container[$offset] = $value;    
    }

Actual result:
--------------
    public function offsetSet($offset, $value) {
        $this->container[$offset] = $value;
    }
