mapAccumR :: (acc -> Word8 -> (acc, Word8)) -> acc -> ByteString -> (acc, ByteString)rawfilepath Data.ByteString.RawFilePath The mapAccumR function behaves like a combination of map and foldr; it applies a function to each element of a ByteString, passing an accumulating parameter from right to left, and returning a final value of this accumulator together with the new ByteString.
mapWithKey :: Ord k => (k -> a -> b) -> RMap k a -> RMap k brec-def Data.Recursive.Map RM.get (RM.mapWithKey (applyFun2 f) m) === M.mapWithKey (applyFun2 f) (RM.get m)

mappings :: RichEnv -> Mappingsrichenv RichEnv Mappings from one existing environment variable name to another.
mappingsToValues :: Environment -> Mappings -> Valuesrichenv RichEnv.Setters Takes an environment variable list and all the name mappings and prepares a set of environment variables according to the RichEnv rules.
