[issue38200] Adding itertools.pairwise to the standard library?

[Vedran Čačić]

I also use it all the time. Most recently in some numerical calculation for successive differences. My main problem is that I'm too often tempted to just zip l with l[1:], thereby restricting the code to sequences, when it would work perfectly well for any iterable. (Just as I sometimes write range(lots of nines) instead of itertools.count() *shame*;)
