Although now that I think about it, if we're just appending to the state, this should possibly be a Writer instead of a State; the interface is simpler.
The problem with this approach is that the hash context isn't a monoid; you can absorb data into the context, but you can't combine two hash contexts to form a new one. Thus, the Writer monad won't work for this purpose.
