In an ideal world there would be a 'deriving Serializable' you
could do on datatypes which would get this right. In a really ideal
world, you could specify the data layout somehow[2a], which would
make integrating Haskell code into a wider distributed network of
processes exchanging binary data a cinch. In a super really ideal
world, you could operate on the packets in place in Haskell where
possible and save the deserialization overhead...
Anyone trying to do any of this?
 deriving picklable?
 DFDL does this for XML / binary data translation.
[2a] Or even dump to arbitrary formats: XML, JSON for concrete
datatypes, mabe use the approach from
(link stolen shamelessly from Lambda the Ultimate) for higher
 Maybe UBL from http://www.erlang.se/workshop/2002/Armstrong.pdf ?
