merlyn, while I can appreciate tersity in many cases, this is not one. I really wish you had at least spent the effort on a list of tie-ins to your linked document -- but that's just me.
broquaint also offered a plug, but then he continued to fullfill the OP's request. Even a quick three sentence tie-in to your document would have been good. Closures are a hard concept for many. Also, I would have at least included a positive emoticon of some sort to reduce the condescendive tone of the reply.
But that's just me. I am aware that you are probably a busy person.
P.S.: I am also curious about why you use the • entity...
