Also, these modules import Data.Monoid, which contains the non-H98 instance Monoid (a -> a), making it (and these) non-portable.
In what sense is instance Monoid (a -> a) not Haskell'98? It looks perfectly OK to me. Is it because the two type variable arguments to (->) are the same? Regards, Malcolm
