What about 'emptyDoc'? Moreover, if you are changing the names of
combinators, then moving them away from Applicative and Arrow would be
a good idea; i.e., don't use <+>, as it already used by ArrowPlus.
Moreover, if you can make a Monoid instance such that `mappend` equals
<>, you would also make the library compatible to a future
introduction of (<>) = mappend.
