You should consider youself as lucky if you completed to port all your
code to Python 3. It's not my case yet :-) (I'm thinking to code that
I have to port, not only code that I wrote myself.)

I confirm that I usually use -b while I'm porting code from Python 2
to Python 3. So, usually I know that I will get Python 3 compatibility
issues. Sometimes, you may still get Python 3 compatibility issues
while the project is already tagged as "compatible with Python 3",
just because you get into a code path which wasn't properyl tested
before.

Well, I don't have a strong opinion on -b.
