Hi Nicolas,
Replying to [comment:4 nthiery]:
> While we are at it, we probably want to implement .one() as a
cached_method. I am not sure about the deletion of trailing whitespaces
outside of the lines you change anyway, as this is subject to making
conflicts.
> Ah, and do we want to do the same for .zero()?
I suspect that question is partially addressed to me, as it may relate
with #11115?
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.
