My one suggestion might be to abstract out the "zippy apply" pattern, like so:

zipApp :: Traversable f => [a -> b] -> f a -> f b zipApp fs = fst . flip runState fs . T.mapM f where f x = ... etc, same as above

Then inlineSeps g = zipApp (id : repeat g), and you can reuse zipApp for other things.

Thanks! This is nicer, indeed. Perhaps, the last piece i'm missed for :)
