Interesting approach, but it doesn't seem to me to be fundamentally different than the BPOS (big pile o' symlinks). Over in Debian-land one of the interesting points against a driver script was that folks like to be able to explicitly override the shebang line interpreter, e.g. $ head /usr/bin/foo #! /usr/bin/python3 -Es $ python3.4 /usr/bin/foo ... One other person mentioned they like to be able to execfile() - or the Python 3 moral equivalent - the /usr/bin script, which obvious would be harder with a sh or binary driver script. -Barry _______________________________________________ Python-Dev mailing list [email protected] http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
