The following function is useful (i have used it a few times):

mapStreamM :: Monad m => (a -> Stream (Of b) m x) -> Stream (Of a) m r -> Stream (Of b) m r
mapStreamM f = S.concats . S.mapsM (\(a :> s) -> return (f a >> return s)

Do people think this would be a good addition
Is there a better implementation
Is there a better name

What's the difference with for? They have somewhat similar signatures, although the one for for is slightly more abstract.
