Unfortunately, that is not a realistic goal for the 2to3 translator. The
goal is to accurately translate 80% of Python code that needs changing,
and issue warnings for the other 20%.

No, you have TWO sets of code. You have the code you write, and the code
you have run through 2to3. Even if 2to3 gives you 100% coverage, which it
won't, you still have two codebases.
