At least one person downvoted the above. If someone who did is reading this: I would be very interested to know why.<p>(I don&#x27;t at all object to being downvoted. But if I&#x27;m thinking incompetently or writing badly or being obnoxious or something, I&#x27;d like to know what&#x27;s wrong so that I can fix it. And I haven&#x27;t been able to figure out what&#x27;s downvote-worthy in the parent of this comment.)
