I was wondering about this:
-- My goal with this instance was to make it work just enough to do what
-- I want when used with the HStringTemplate library.
instance Data UUID where
toConstr uu = mkConstr uuidType (show uu)  (error "fixity")
gunfold _ _ = error "gunfold"
dataTypeOf _ = uuidType
Is there any reason not to just say "deriving Data" in the type declaration?
