I am continuing a discussion in a new post.
The issue is that if we take a class such as graphs the instances are
mutable.
It would be useful to have a version which was immutable and therefore
hashable.
For example, we could then use CombinatorialFreeModule to construct

sage: (1/R(x)).parent()

The fraction field of Z[[x]] would have to contain Q, so cannot by the
