If passing those properties by reference to functions works, perfect. I'll NULL it out then.
I'm not sure what you mean by passing by reference. If you want to do real by reference work then you have to use object proxies and ->set() ->get() callbacks. In general, the semantics of by reference is mainly designed for regular PHP objects and zval **'s (i.e. PHP values).
