Thanks I do not know how my pyflakes script missed that. I don't see the doctest failutre though in that report. I updated this removing the unused import

see the "shortlog" link for the doctest failures (something moved, should be easy to fix by changing some imports)

Ohh I see thanks, repr_lincomb was changed in develop. I'll fix it right away.

Ok, now it's green. I don't think I can do much about the startup time.

I think this is good to go into Sage. We can continue to make improvements to the code here as things progress in the later tickets. With the current version, it is flexible enough to change without major difficulties IMO.

Thank you for all your hard work and discussions on this ticket.

Great, thanks for your work and time. I'll prepare the other tickets right away. The examples ones should be easy. The vertex algebras one will take me a little bit cause I'll implement the same category changes that you asked in this one. Do you have an idea for the stub category name?

Ah, I see that you already requested a rebase of the examples ticket. Since no one seems to care about commit messages, do you think I can merge this ticket into that one? It would be much easier to merge this than to rebase. Otherwise I might get away with first merging, reset and then rebase with rerere.

I am not sure what the base category should be called. However, it can be a fairly generic and/or descriptive name as it is not something the user will see too much of.

We can discuss more on that ticket.

Thanks for adding the section in the release tours! Looking great.

Just a quick note on is_even_odd -- this strikes me as nonstandard naming from a Python point of view. One would expect that a method that starts with is_ returns a boolean. Would it be better to rename it to is_odd and return a boolean, or to rename it to something like parity?

That may be hard to change. It was forced on me by SuperModules.
