Re: Proposal: add unzips for Data.Sequence

This idea has been around a while: https://hackage.haskell.org/package/category-extras-0.52.1/docs/Control-Func... Here is an article: http://comonad.com/reader/2008/zipping-and-unzipping-functors/ Note that all functors give unzip: \x -> (fmap fst x, fmap snd x) On Fri, Jan 12, 2018 at 1:28 PM, David Feuer wrote:

Paolo G. Giarrusso (Blaisorblade) would like to add an unzip function to Data.Sequence. I agree. I propose adding

unzip :: Seq (a,b) -> (Seq a, Seq b)

unzipWith :: (x -> (a, b)) -> Seq x -> (Seq a, Seq b)

Does anyone object?
