I am not sure that is the case. I think library authors would be better
suited to provide meaningful error messages and decide when

Folks,
How do I fix this?
data Prop = forall a b.(Eq a, Show a) = Attr a := a
data Attr a = Attr String
(a - Dynamic, Dynamic - Maybe a)
(PU a)
type Props = M.Map String (Int, Prop)
instance Ord (Int, Prop) where
compare (a, _) (b, _)
| a == b = EQ
| a b = GT
This gets me pretty close. I now have to figure out how to return a
PU Props instead of a PU [Prop] which is what it's returning. Still,
it's a huge step forward.
props :: Props - PU Props
props m = props' $ sort $ M.toList m
where props' [] = lift []
props' ((_, (_, x)):xs) =

Folks,
How can I create a generic pickler that's parameterized on type and
constructor?
I define types like this:
newtype AvgPot = AvgPot Word64 deriving (Show, Typeable)
newtype NumberOfPlayers = NumberOfPlayers Word16 deriving (Show,
Typeable)
and then have a lot of boiler-plate code
16 matches
