+1 to just generalizing filterM in Data.Sequence On Sun, Dec 28, 2014 at 12:22 AM, David Feuer wrote:

This can be given exactly the same implementation as the one for lists:

filterM :: (Applicative f) => (a -> f Bool) -> Seq a -> f (Seq a) filterM p = foldr go (pure empty) where go x r = f <$> p x <*> r where f flg ys = if flg then x <| ys else ys
