Comment(by atagar):

 > So... um... you mean, run a Py2 script which converts the code base,
 including itself, to Py3, then execs Py3 on the newly-converted version of
 the running script?

 Somehow I get the sense that you're not quite thrilled with this idea. :P

 It would largely be the same as the shell script you mentioned. The only
 difference is that it lives in test_runner.py, in essence...

 {{{
 python3_destination = os.path.join(CONFIG["integ.test_directory"],
 'python3')
 os.makedirs(python3_destination)
 system.call("2to3 --write --no-diffs --nobackups --write-unchanged-files
 --output-dir=%s stem test run_tests.py" % python3_destination)
 system.call("python3 %s/run_tests.py %s" % (python3_destination, "
 ".join(sys.argv[1:]))
 shutil.rmtree(python3_destination, ignore_errors = True)
 sys.exit(0) # TODO: use the exit status of the above call instead
 }}}

 The advantages of this are...

 * '--python3' can be a testing argument just like any other.
 * No need to have yet another little shell script floating around (fewer
 of those mean less clutter, which I like).

 Feel free to talk me down from the ledge. ;)
