Good--that's the behavior without the "one variable fix" patch :)
This morning I had an idea for helping this code get reviewed (note that
the ticket turns 4 at the end of this month): Could we break the review
process into several manageable pieces, and have different people take
responsibility for different parts? For example, I'd propose something
like the following:
1. The underlying concept of the implementation (foreground ring &
background ring, etc.)
1. Documentation and tests
1. `multi_power_series_ring.py`: the code accurately does what it claims
to do
1. `multi_power_series_ring_element.py`: the code accurately does what it
claims to do
1. Integration with the rest of sage: construction and use of
`PowerSeriesRings` works correctly, and parallels behavior of polynomial
rings
1. Completeness of the review: do these pieces give an essentially
complete breakdown of the review?
