I've actually been partial to the term "clob" since the moment I came up with the idea — the first two letters of each word in the term "closure object". It hadn't occurred to me to invent a whole new jargon for it. That'd be fun, and probably kind of effective if I were to attempt to market the whole idea and sell books about it, but I'm a long way from that right now.

Let's call them "clobs" for now. More terminology can come later, when I figure out what the specific actions are that would be described by the terms.
