As mentioned in my email to the mailing list, I'd like to see more of a description here. Also, try to avoid being too prescriptive, "it's a good idea" is something others can easily refute. It would be better to say that some prefer to have their variables alphabetized and then show an example of it being alphabetized and not. And then provide a bit of a counter-argument, those who don't like vars to be alphabetized think that it adds complexity to managing variable lists and that alphabetizing variables doesn't add much value.
