We use 3to2 to provide a python2 version of an internal library. We've run into a unicode problem with one of the conversions because of a line in
httplib.py from python 2.7 (which is harder to get changed).
Would you be amenable to a pull request to add a feature that allows transformations to be disabled on a per-line basis with inline comments?
I was thinking of something drawing inspiration from tools like flake8 and rubocop:
str("foo") # 3to2:disable str
