Can I ask that the name Reverse not be used? I have a newtype wrapper
for Ord by that name which I'm planning to propose adding to base (in a
month or so, once the semester ends so I have the time). I can't think
of another good name for the obvious Ord transformer, though there are a
few other names which would make sense for Applicatives.
