It seems like 3to2 needs to learn how to remove annotations and dictionary comprehensions first. Unfortunately hacking 3to2 is a bit beyond me. Sounds like a great idea though.

I had initially thought about making it a goal that 2to3 -> 3to2 code would look the same as the original, but as I learned more, I conceded that it would be unrealistic and impractical.
