Another problem is that it does not cover special cases where, for
example you compile Python with SSL and without. You don't want them
to share user installed libs.

Upstream does not handle this case, so I do not see a need to handle
this in guix. If we find a way, this would be find. But prior to solving
the optional we should solve the compulsory :-)

  https://github.com/python/cpython/blob/master/configure#L1543

and there are many other options which define the behaviour of the
interpreter. We don't use them in GNU Guix, but it does not mean we
should not think about it/allow it.

Now I understand you point: If there are two variants of e.g Python 3.5 available, but there is only one GUIX-PYTHONHOME-3.5 variable, this will intermix the environments again.

You are right!

Adding the hash would indeed be a good solution :-)
