Replying to [comment:12 pernici]:
> Another observation: I suspect that total degree multivariate power
series implemented with PARI would require changes in the implementation
in ticket #1956, not only in this patch; the background power series ring
would not be `PowerSeriesRing(self.__poly_ring, T)`, but a PARI power
series. For certain rings probably one cannot use PARI (e.g. symbolic
rings?), then the current implementation should be used instead.

class using PARI; this would be the argument of another ticket, if someone
is interested in working on it; ticket #1956 and this patch would deal
with the generic implementation.
This sounds like a good idea -- thanks for clarifying. The improvements
you've made are certainly worth finishing and including in sage.
