Yes, the submitter broke the HN guidelines by editorializing the title. On the other hand, the article's official title is uninformative. So I replaced it with the sentence from the article that most seems to describe its content (shortened to fit 80 chars). If anyone can suggest a better title, I'll change it again.
Not sure if you're the one who changed it, but the " Trapperkeeper is a new Clojure framework [...]" title works fine and is much less misleading imho.
