The instance for "Functor (Either ParserError)" disappeared. Is that intentional?
The instance is still in Control.Monad.Instances. The problem with the instance is that Haskell 98 doesn't say that it exists, so we can't put it with either the Functor or Either definitions. You were probably indirectly importing Control.Monad.Instances before, but other changes now mean that you no longer are. Thanks Ian
