This asymmetry bothers me too. It makes me think that datetime
handling belongs at a different level of abstraction, something
that knows about the structure of the data being serialised or
deserialised.

Java's JSON libraries have a mechanism where you can give it
a class and a lump of JSON and it will figure out from runtime
type information what to do. It seems like we should be able
to do something similar using type annotations.
