You mean <http://www.eros-os.org/pipermail/cap-talk/2006-December/006721.html>?

I thought that article was hopelessly confused. Yes, languages and operating
systems tend to use different implementations of objects, but they are
implementing the same concept. The level of abstraction at which there
may (or may not) exist v-tables or data-bytes in capability representations,
simply is not relevant to the definition of an object.
