Comment(by nthiery):
Replying to [comment:38 SimonKing]:
> Well, mostly harmless. Some involve to implement the category framework
for uni- and multivariate power series rings. Multivariate power series
rings was a recent addition - so, why has it not been done in the first
place?
Still way too much code using prehistoric stuff; so devs and reviewers
don't take the right examples to start from.
> It seems that the 242 Steenrod errors are mostly gone. At least,
`TestSuite(SteenrodAlgebra(2)).run()` works.
Yippee!
> Time to call it a day...
