[Python-ideas] Make dataclass aware that it might be used with Enum

July 6, 2022

      Perhaps, this has already been addressed in a newer release (?) but in Python 3.9, making `@dataclass` work with `Enum` is a bit awkward.

Currently, it order to make it work, I have to:
1. Pass `init=False` to `@dataclass` and hand-write the `__init__` method
2. Pass `repr=False` to `@dataclass` and use `Enum`'s representation or write a custom __repr__

Example:
In [72]: @dataclass(frozen=True, init=False, repr=False)
    ...: class Creature(Enum):
    ...:     legs: int
    ...:     size: str
    ...:     Beetle = (6, 'small')
    ...:     Dog = (4, 'medium')
    ...:     def __init__(self, legs, size):
    ...:         self.legs = legs
    ...:         self.size = size
    ...: 

In [73]: Creature.Dog
Out[73]: <Creature.Dog: (4, 'medium')>
