That's funny, I was expecting the opposite behavior:

    fart => [ :fart ]
    fart 1 => [ :fart, 1 ]
    fart 1, 2 => [ :fart, 1, 2 ]

Seems more lispy to me, and from a quick glance I can't see where it would break.

Yes, I prefer this, definitely more lispy.

I blame seeing too much of clojure's "defn fart [ args ]" syntax ;-)
