As Chris pointed out though, the real problem with the "repeatedly run
2to3" workflow is that it can make interpreting tracebacks from the
field *really* hard. That's where Antoine's suggested approach may be
better - use 2to3 to do the initial mechanical update in a new branch,
then subsequently use a process similar to what we do ourselves for
the standard library (i.e. update the 2.x and 3.x versions in
parallel, perhaps using 2to3 on a few files if they have changed
substantially in a particular patch).
