Yes. I have came back to looking at the binary package, the only thing is I
think I have to build my own primatives with it as it is big-endian, where
ActionScript Byte Code format is little-endian. It does provide some
little-endian functions but they are not brought to the surface. It also
seems to roll its own serializations.

I am maybe looking at doing my own specialized set of types and binary
backend as there are drawback with each of the existing solutions.

  - Data.Storable.Endian - peeks and pokes rather than put/get
  - Data.Word24 - peeks and pokes rather than put/get
  - Data.Binary - big-endian

ABC format may best be supported by a specific set of serialization types.

On a different note thinking outside this problem, I would like IO_LE and
IO_BE types if that could be make to work.
