Subject: overload extension
From: LingWitt@insightbb.com

The methods of an object that has been passed to the overload() 
function lose their ability to have parameters passed by reference. For 
example:

class Foo
{
     function hello(&$array)
     {
         $array[] = "hello";
     }
}

$array = null;
$foo = & new foo();
$foo->hello($array);
print_r($array)

Output:
Array
(
     [0] => hello
)

class Foo extends PEAR_Autoloader
{
     function hello(&$array)
     {
         $array[] = "hello";
     }
}

$array = null;
$foo = & new foo();
$foo->hello($array);
print_r($array)

Output:

Nothing!
