Hi Café,
I have a DSL like this:
data Exp where
OnEvent :: EventName -> (Int -> Exp) -> Exp
(...)

The "OnEvent" element carries a function (the handler to be called when the event happens), and that makes my DSL non showable/serializable.
How could I fix that? This is a real handicap not to be able to serialize the state of my whole application because of that :)

Thanks,
Corentin
