Dear all, Where is the Monad instance declaration of Either e?
>From the description of Control.Monad.Error, I deduce that Either e is an instance of Monad. http://haskell.org/ghc/docs/latest/html/libraries/mtl/Control-Monad-Error.html class Monad m => MonadError e m | m -> e where ... Error e => MonadError e (Either e) But, I cannot find the Monad instance declaration of Either anywhere.
