[Haskell-cafe] serialize an unknown type

[Alberto G. Corona]

You can include the type in the serialized string. When recovering you can
read the type and use to look for the appropriate deserializer in a lookup
table where you have registered the deserializer.

I use this trick in the IDynamic package,. that serializes-deserializes
dynamic types:
