Oh. That explains the 'slow' complaint.

However, 2to3 tools could be developed which are based on 2to3/lib2to3 and are incremental in nature; then as you edit and save a file, its processed version could be available very shortly afterwards (since we only need to translate the file that was saved)

I had assumed that people were aleady running 2to3 on a per edited file basis already. On a multi-core machine, I would think it possible to run 2to3 and then a test on the result in a separate process while tests are running on the 2.x version.
