Oh and how /bin/bash is bash3 on macOS instead of the contemporary bash5 by default. And how sh is dash on Debian, or Ubuntu, I forgot. Some of the reasons why

Oh and how /bin/bash is bash3 on macOS instead of the contemporary bash5 by default. And how sh is dash on Debian, or Ubuntu, I forgot. Some of the reasons why I would prefer python3 scripts (or perl) over sh or bash

Pretty annoying to reliably #! to python3 as well. Is it /usr/bin/python or python3?

  That's my worst. I think generally python3 is safe (if unnecessary) today? But for how long do we have to keep that around? Can we now say Well python2 is EOL so python should certainly be v3+? It is of course a more general issue with shebangs that it's a very loose 'dynamically linked' coupling, not necessarily judt affecting language version but environment/libraries too, it just seems particularly problematic or prevalent with python.

    That's not the point - 'or /usr/bin/env python?'
