[Haskell-cafe] serialize an unknown type

[Corentin Dupont]

Hi the list!
I have a simple question, how can I serialize/deserialize a structure like
this:

data InputChoice c  deriving Typeable
data Event a where
    InputChoice :: (Eq c, Show c) => [c] -> c -> Event (InputChoice c)
 (...)

I'd like that the values of type "c" get serialized to a String... That's
the easy part, but for deserializing, oops!

Cheers,
Corentin
