Comment (by dfeuer):

 Er .... actually, the situation is more complex than I thought.
 Specifically, it sometimes does make sense to do it somewhat like this for
 something like the `[]` applicative. Ugh. On the other hand, I don't
 necessarily think traversing an `Array` in `[]` is a terribly sane thing
 to do.
