I've posted a new version of PEP 557, it should soon be available at
https://www.python.org/dev/peps/pep-0557/.
The only significant changes since the last version are:
- changing the "compare" parameter to be "order", since that more
accurately reflects what it does.
- Having the combination of "eq=False" and "order=True" raise an
exception instead of silently changing eq to True.
There were no other issues raised with the previous version of the PEP.
Not quite; I also raised the issue of isdataclass(ADataClass) returning
False. I still think that's likely to be a cause of bug reports if left
as-is.
Oops, sorry about that!
I think you're probably right. attr.has(), which is the equivalent attrs
API, returns True for both classes and instances (although
interestingly, the code only talks about it working on classes).
