[$] Revisiting PEP 394

With the uptake of Python 3 (and the imminent end of life for
Python 2.7), there is a question of
which 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 PEP
that relayed the recommendations of the Python core developers to Linux
distributions and others in a similar
position about which version
to point python to. Now, Petr Viktorin, one of the authors of the
PEP, would like to
revisit
those recommendations, which is something that is suggested
in the PEP
itself.
