> I suspect that question is partially addressed to me, as it may relate
with #11115?
Yup. And to detect potential conflicts with the ongoing changes in rings
and such.
> I didn't look at the patch. But if you mean to make .zero() and .one() a
cached method of the parent class of a category, then in fact #11115 is
needed in order to make the cache work on those parent structures that do
not allow attribute assignment.
