interested:
http://hackage.haskell.org/packages/archive/iteratee/0.3.5/doc/html/src/Data... It would look like attoparsec's resumable parser: data Result a = Fail !ByteString

bytestring can be implemented on top easily, as can decoding a sequence
lazily. Like attoparsec you'll probably want to write some other utility functions
for working with Results. Attoparsec defines feed, parseWith, maybeResult,
and eitherResult. I think you'll want something similar here. I imagine you could fairly easily interface it with iteratee too. Yes that should be easy given the above API. See for example the
attoparsec-iteratee package.
Once that work is done how will binary differ from cereal? How will I know
which one to pick?
Thanks,
