No, no, no. Comma first variable listing is the worst thing ever in the history of the world.
Having the comma in the proper place has such a negligible cost (oh no I might have to delete the comma on the last element and add it to the formerly-last element!), and having it like this looks so god awful and doesn't really save you anything if you're swapping the first element instead of the last one.
