Dataclasses are a sweet feature that I can see getting wide adoption pretty quickly. This said, they have a backport and it's mostly just sugar, so I expect one could probably get them working on 3.6 pypy.

http://attrs.org is the inspiration for dataclasses, but attrs has more features and is available on all versions.

Dataclasses work in 3.6 with pip pkg I believe.
