How about making Data.Monoid portable, by replacing the a -> a instance with one for a newtype?
Although this would change the interface of Data.Monoid a tiny bit, this seems the most attractive solution. I seriously doubt that the a -> a instance is really widely used... Do you have a concrete newtype in mind? I'm currently not sure if we already have something like this... Cheers, S.
