1. mapWriterT :: (m (a, w) -> n (b, w')) -> WriterT w m a -> WriterT w' n b

   dunai	Control.Monad.Trans.MSF.Writer

   Map both the return value and output of a computation using the given function.

   • runWriterT (mapWriterT f m) = f
     (runWriterT m)

2. mapMaybeS :: forall (m :: Type -> Type) a b . Monad m => MSF m a b -> MSF m (Maybe a) (Maybe b)

   dunai	Data.MonadicStreamFunction.Util

   Apply an MSF to every input. Freezes temporarily if the input is Nothing, and continues as soon as a Just is received.

3. mappendFrom :: forall n (m :: Type -> Type) . (Monoid n, Monad m) => n -> MSF m n n

   dunai	Data.MonadicStreamFunction.Util

   Accumulate the inputs, starting from an initial monoid value.

4. mappendS :: forall n (m :: Type -> Type) . (Monoid n, Monad m) => MSF m n n

   dunai	Data.MonadicStreamFunction.Util

   Accumulate the inputs, starting from mempty.

5. mapName :: (n -> n') -> Expr n v e -> Expr n' v e

   egison-pattern-src	Language.Egison.Syntax.Pattern.Combinator

   Map over n in Expr n v e.

6. mapValueExpr :: (e -> e') -> Expr n v e -> Expr n v e'

   egison-pattern-src	Language.Egison.Syntax.Pattern.Combinator

   Map over e in Expr n v e.

7. mapVarName :: (v -> v') -> Expr n v e -> Expr n v' e

   egison-pattern-src	Language.Egison.Syntax.Pattern.Combinator

   Map over v in Expr n v e.

8. mapBoth :: (a -> c) -> (b -> d) -> Either a b -> Either c d

   either-unwrap	Data.Either.Unwrap

   The mapBoth function takes two functions and applies the first if iff the value takes the form 'Left _' and the second if the value takes the form 'Right _'.

9. mapLeft :: (a -> c) -> Either a b -> Either c b

   either-unwrap	Data.Either.Unwrap

   The mapLeft function takes a function and applies it to an Either value iff the value takes the form 'Left _'.

10. mapRight :: (b -> c) -> Either a b -> Either a c

    either-unwrap	Data.Either.Unwrap

    The mapLeft function takes a function and applies it to an Either value iff the value takes the form 'Left _'.
