There was a problem hiding this comment.
itertools.pairwise is new in Python 3.10, so this rule should be restricted to target_version >= PyVersion::Py310.
Should we also check for zip(a[:-1], a[1:])?

@charliermarsh just have to get the new changes re-reviewed - I changed the logic for determining successive pairs to simply be a difference of 1 between start of first/second slices. That'll allow us to pick up cases like |

Fixes #3297.
We ensure that the two arguments to
zip()match and that the lower bound of the slice is 1, if the second argument is a slice. Otherwise, we wouldn't be able to guarantee that the request being made is for successive pairs.
