I am proposing inclusion into base to make it readily available out of the box. I think it would fit rather well together with the other zips in Data.List.
But then once you go there, I have a list library with 7 more zip variants, 7 more group variants, 5 more partition variants, some more spans and breaks and viewR and duplicate dropping and merges and splits and etc. And of course I also think they're all useful and I use them all the time, so surely worth including in Data.List. I suspect just about everyone has a personal library of list utilities, all of which are general purpose and useful to that person. Where to stop? Interestingly I don't have mapAdjacent because I've never needed it, but I have zipNext and zipPrev, which I do use frequently, so there's also quite a bit of bikeshedding potential on the general vs. specific scale. I don't mind keeping a local library of things that adapted for my personal style.
