Comment (by AlexanderDreyer):
> Fixing the .index() function to avoid this would in any case break
Alexander's patch. If I understand correctly, his patch relies on this
"feature"
Well, it would break much more since the the Sage uses `pbori.pyx` also to
interconnect betweento `PolyBoRi`'s python modules and its C++-based
kernel (supplementing `PolyBoRi`'s original interface here). As long as
Sage-only and `PolyBoRi`-only function are not mixed, this should not be a
problem.
But I just realized, that `.variable()` is reordered (unlike `.gen()` it
shouldn't), so I'll check this for consistency.
