Description:
------------
>From outside a class, accessing a variable via a __get is identical to
accessing one via a public member:

$publ->varr
vs.
$gets->varr

When trying to pass by reference, I would expect the corresponding
__set to be called when the value originaly came from a __get. Instead,
there is a Fatal error.

Reproduce code:
---------------
class PublicVar {
        public $varr;
}

class GetSetter {
        
        protected $data = array();
        
        function __get($key) {
                return $this->data[$key];
        }
        
        function __set($key, $value) {
                $this->data[$key] = $value;
        }
}

function set_by_ref(&$variable) {
        $variable = 'has been set, ';
}

$publ = new PublicVar();
set_by_ref($publ->varr);
echo $publ->varr;

$gets = new GetSetter();
set_by_ref($gets->varr);
echo $gets->varr;

Expected result:
----------------
has been set, has been set, 

Actual result:
--------------
has been set
Fatal error: Cannot access undefined property for object with
overloaded property access in C:\eclipse\workspace\tmote\tmp_byref.php
on line 27
