Ah, and I'd forget. I have the following dream:

  /etc/env.d/python/python2
  /etc/env.d/python/python3
  /etc/env.d/python/config -> python2

So, python{2,3} keep the per-version interpreters, and config is just
a symlink to one of them. Two bird with one stone -- readlink to get
which group is enabled, cat to get the exact interpreter. I'm proud
of myself!
