New submission from Edward Jones <edwardrjone...@gmail.com>:
When `__init__` is called for a class which 1) is annotated with `@dataclasses.dataclass(frozen=True)` and 2) has a attribute named `object` a TypeError is raised because `object` is overridden for the local scope and as a result `__setattr__` is called on the passed in argument value instead of the standard `object` base type. I was able to reproduce this in a Docker container running https://github.com/docker-library/python/blob/7a794688c7246e7eff898f5288716a3e7dc08484/3.7/stretch/Dockerfile with the attached .py file.
