Comment:
I found that the function `new_NRing`, that is supposed to return a valid
`NCPolynomialRing_plural` out of a ring wrap, is broken. Important data,
namely the matrices c and d, are left as `None`. Hence, for a ring
produced with `new_NRing`, pickling won't work at all.
The question is whether we can leave it broken for now, and fix it
separately, or leave this ticket open and "needs work". How shall we
proceed?
