Alternately we could just hand-roll the instances so it doesn't change
whether it gets imported if the user writes
import Control.Applicative (Const(..))
but I agree with simplifying the presentation.

It would be handy for Control.Applicative.Const to have the various derivable instances (Eq, Ord, Read, Show).
In particular Read and Show would make debugging easier.
I'd suggest redefining getConst as a function rather than a field to make the derived Read and Show instances simpler. Ditto WrappedMonad. _______________________________________________ Libraries mailing list Libraries@haskell.org http://www.haskell.org/mailman/listinfo/libraries
