Replying to [comment:13 vbraun]:
> I thought we might be able to add the torus factor rays at the end of
`fan.rays()`, so that we always have a 1-1 correspondence between rays and
homogeneous variables. The list of 1-cones starts with the rays but does
not include the torus factor rays. But I haven't tried this to see how it
will work out.
That's an interesting idea, but we should be very careful if we implement
it: there may be places where the rays of the fan are supposed to be
"honest" and I am not quite sure how to search for such places. But maybe
I just worry too much.

I certainly would not mind ;-) And thanks for reviewing #10793!
