Comment (by SimonKing):
Arrgh. That's nasty. The reason for the doctest problems is that meanwhile
there are multivariate power series rings -- but there are still no
multivariate Laurent series rings.
Spontaneously, I suggest a temporary work-around: In the case of
multivariate case, the old behaviour (namely: using a formal fraction
field) should be used, until multivariate Laurent series are available.
