[$] Revisiting PEP 394

With the uptake of Python 3 (and the imminent end of life forPython 2.7), there is a question ofwhich version of Python a user should get when they type "python"at the command line or have it as part of a shebang("#!") line in a script. Back in 2011, PEP 394 ("The'python' Command on Unix-Like Systems") was created as an informational PEPthat relayed the recommendations of the Python core developers to Linuxdistributions and others in a similar position about which versionto point python to. Now, Petr Viktorin, one of the authors of thePEP, would like to revisitthose recommendations, which is something that is suggestedin the PEP itself.
