Thanks for pinging. I am now trying to find a good replacement for that
test.
The problem is: We need an object that has a "list" method (after all, the
comments for the test state that `F.list()` would run forever), and we
need one that does not know whether it is finite or not.
So, we can not use fraction fields, since they know whether they are
finite. And we can't use, e.g., quotient rings of multivariate polynomial
rings, since they do not support iteration.
Do you have any idea what one could use instead?
