[Python-Dev] Third and hopefully final post: PEP 557, Data Classes

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.

So with that, I think it's ready for a pronouncement.

Eric.
