 Description:
------------
Slightly modifying a Harry Fuecks's sample from sitepoint.com on implemening the ArrayAccess interface, I get some unrelated error.
Maybe it's a documentation bug again...
Reproduce code:
---------------
<?php
class Article implements ArrayAccess {
    public $title;
    function __construct($title) {
        $this->title = $title;
    }
    function offsetSet($key, $value){
            $this->{$key} = &$value;
    }
    function offsetGet($key){
            return $this->{$key};
    }
    function offsetUnset($key){
            unset($this->{$key});
    }
    function offsetExists($offset) {
        return array_key_exists($offset,get_object_vars($this));
    }
}
// Create the object
$A = new Article('SPL Rocks');
// Change the title using array syntax using reference
$str = 'SPL _really_ rocks';
$A['title'] =&$str;
// Check what it looks like again
print_r($A);
?>
Expected result:
----------------
Article Object
(
    [title] => SPL _really_ rocks
)
Actual result:
--------------
Fatal error:  Objects used as arrays in post/pre increment/decrement must return values by reference in test.php on line 27
There was no increment/decrement operations used.
It would be _much_ better if it would be allowed to write
    function offsetSet($key, &$value){...}

P.S. I am not allowed to define function offsetGet($key)as "function &offsetGet($key){...}" to return the value by reference due to the requirements of the ArrayAccess interface.
