I was not following this discussion, so I might be speaking out of ignorance, but I thing you are underestimating the problems of reference counting again. Circular references break it, and when comes to RAII, you probably loose the ordering guarantees it needs if you implement some kind of algorithm to deal with cycles. Another option is trust the program be smart enough not to create cycles (weark references can help a lot here), but if the RC is hidden in the language it can be a little hard to remember this restriction. -- Leandro Lucarella (luca) | Blog colectivo: http://www.mazziblog.com.ar/blog/ ---------------------------------------------------------------------------- GPG Key: 5F5A8D05 (F8CD F9A7 BF00 5431 4145 104C 949E BFB6 5F5A 8D05) ----------------------------------------------------------------------------
