Chris, not everything you dislike is anti-Python FUD.

Dominik, if you want something like Python 2.7, you likely should try
Tauthon or Pypy2.  Don't expect pip to work well on Tauthon; last I heard
that was not happening.  Also Pypy2 has some issues with C extension
modules, and I'm not confident it'll pip well either.  It's very worthwhile
to move to 3.x, but CPython has a rather sad compatibility story when it
comes to C extension modules; hopefully CFFI is going to fix that in the
long term. If you're avoiding porting pure Python code, then that feels to
me a bit like foot dragging, as the pure Python changes are not that big
and are pretty much limited to the 2.7 -> 3.0 transition.

I like to build versions of Python from 0.9 to 3.10alpha, for the sake of
quickly ascertaining what features were introduced in what versions of
CPython.  IOW, there are good reasons to keep around old Pythons.  Python
history is interesting.
