Hi, I would like to revive this issue and have added the following comment to Lib/collections.py within issue10225-py3k.diff: The \n at the end of this line (and others in this docstring) is used to create an empty line after this line. Is there a reason to use \n instead of simply having the empty line? That makes it more readable. Otherwise, I have reviewed the changes in both diffs and think they are good to go.
