[Haskell-cafe] Make a DSL serializable

[Alberto G. Corona]

That is the advantage of recording the sequence of events instead of the
final state: that the  state don´t need to be seriallizable. And this
indeed the way to serlize something that can be decomposed in events. I
think that this is elegant.. Specially if the events  and the state are
elements of a Monoid instance.
