  At present, I am not totally convinced of Iteratee/Enumerator.
  Why aren't there any functor instances anywhere? Why do
  filestreams and lists present distinct interfaces? A stream
  computation is a stream computation; the effect of pulling an
  item off the stream and handling it is sequenced in these
  computations so it seems like a monad transformer is in order.
  So I am just going to keep trying until I can make that
  transformer.
