Maybe python2 --enable-print-parentheses and other flags could have been useful to slowly detect future issues on python 2 code.

  Python 2.6 has from __future__ import print_function. There the saving of implementation effort would be not supporting print statements in 3.0.

    Nice it actually gives "SyntaxError: invalid syntax", but then it affects all the imported libraries so I still prefer the per-file way as a transition.

      __future__ imports are per file. A few posts up you were proposing an interpreter-wide switch. Did you change your mind?

        Awesome. I think both are great, first doing file-per-file and once it's working switching the global switch is a pretty good transition workflow.
