My apologies. I totally take the blame for that, as I had volunteered
to review it. In the mean time, I got completely burned out by the
category project, whose reviewers got burned out by ... Thanks for
getting back to us.
The referring need to handle the merging with the lazy power series
that Mike implemented for species (LazyPowerSeriesRing, in
sage.combinat.species.series). I was hoping that Mike would comment on
this first. Mike?????
I really would like to see progress on lazy power series, and I know
how much work you put into that. I still don't have a time line for
when I could do this though. So volunteers to take over the job are
most welcome!
What about you Ralf? You have the expertise with implementing such
lazy power series (in aldor), and what's needed out of them for
species.
Henryk: in the mean time, could you please create a ticket on trac for
this and, if possible, try to evaluate how much work would be needed
to use your lazy power series in the species code?
Cheers,
Nicolas
