Agile development and unittests.
Which I am all for. So the issue is not 3.3 versus 3.1/2, but development versus installation. I somehow did not get that reading the PEP but it seems a crucial point in its favor.
An installation hook means that you need to install the package before running the tests. Which is fine for CI but horrible during development. "python3 run-tests.py" beats "make venv; install library; run testsuite" anytime in terms of development speed.
That I can appreciate. It makes programming more fun. I presume you are saying that you would run the 'Python 3' tests quickly with 3.3 in your normal development cycle. Then, if you want your library to also run under 3.1/2, only occasionally (daily?) check that they also run under a 3.1/2 installation. That *does* make sense to me. -- Terry Jan Reedy
