Glad to hear it! If you feel capable of reviewing some part of the patch,
that would be *greatly* appreciated. Here is the current status of the
various items:
1. Sage passes all doctests with this patch
(positive review; buildbot)
2. All code is documented and doctested thoroughly; documentation builds
without error or warning
(needs review)
3. The underlying concept of the implementation (a wrapper for certain
univariate power series over multivariate polynomials) is sound
(positive review; Mario Pernici)
4. multi_power_series_ring.py: the code accurately does what it claims to
do
(needs review)
5. multi_power_series_ring_element.py: the code accurately does what it
claims to do
(needs review)
6. Integration with the rest of sage: construction and use of
`PowerSeriesRings` works correctly, and parallels behavior of polynomial
rings
(needs review)
7. Performance: the multivariate power series arithmetic is fast enough to
be included in Sage
(positive review; Mario Pernici)
8. Coding: the code is free from obvious inefficiencies in error handling,
memory management, etc.
(needs review)
9. The items on this list constitute a complete review
(needs review)
