As happenstance would have it, somehow I accidentally posted this part of my next post whilst still editing it. The fact that I cannot remove this error because of inane web policies illustrates the arcane nature of most forum software. (note: HN is not alone in this regard, it's typical of most.) The relevant issue here is that the time of this post there is no other post in reply to this error and thus I ought to be able to remove it without disturbing any other part of the forum per se — ah but alas it's not possible as I've already exceeded some arbitrary time limit even though it has absolutely no relevance in this instance. My full post further amplifies my reasons.
