Ah, I misunderstood. Yeah, that's silly and I think it's usually a bit tongue-in-cheek or playful. When it's not it's very, very lame. In the Lisp world I associate it with SICP, which I read as falling in the former category. Lispers (and associates) who write after that style are doing so in imitation of that, I suppose, or of some prior work that it also cribbed from that I'm not aware of.
