dataclasses.dataclass

The decorator dataclass from the module dataclasses is the hardest to implement of them all.

The decorator dataclass does a lot of different things, so this project is a standing invitation for what is essentially a rewrite of the standard module dataclasses.

As a good first exercise, try to create a decorator dataclass that just adds the dunder methods __init__, __repr__, and __eq__, to the class decorated by dataclass. Assume the class attributes specified in the data class are all built-in atomic types like Booleans, integers, floats, and strings.
