[arch-general] a plea for python 2

I personally don't think it is a proper fix - I think it is not a fix
at all. My opinion is that Python3 is sufficiently different from
Python2 to be considered a new language, not just a new version of old
(thus it would be appropriate to use new name, 'python3', for it,
leaving 'python' forever referring to python2). (That is, desire to be
on the bleeding edge does not warrant breaking existing software)

If I were you, I would probably stop putting shebangs into my Python
scripts (so that they would be not executables), and write a shell
wrapper script for every python script that figures out during runtime
how python2 executable is called, and call python2 script using this
python executables (or write single script with symbolic links to it
with different names and use $0 shell variable to find which python
script to call).
