Comment:
- the problem this ticket is supposed to address is about the .subs()
method changing the parent (see the linked thread). Is it fixed ?
- the problem actually comes from an inconsistent subs for polynomials.
This is usually called a dependency, and there is even a field for that on
trac, so that we ensure the actual problem get solved.
- having ticket merged that fast is a good way not to fix the real
problem.
