Well, in a way you pass a "handle" by copy. So you copy the handle, but
both handles point to the same object.
The difference is:
$foo = new Class;
$bar =& $foo;
$bar = "bar";
var_dump($foo) will say "bar".
Without the &, it will still be an object of the class Class.
But as you only copy a handle, both $foo and $bar point to the same
object.
