MonadPlus Reform

21 Mar 2006


      Does this come under the "standard libraries" topic? I would like to see 
the MonadPlus class disambiguated:

class Monad m => MonadZero m where
    mzero :: m a
class MonadZero m => MonadPlus m where
    mplus :: m a -> m a -> m a
class MonadZero m => MonadOr m where
    morelse :: m a -> m a -> m a
