Speaking as someone who's not into dataclasses:
This whole thread seems to be about spelling the initilizer's function
signature as a class body. Have you considered going in the opposite
direction, i. e. writing something like
@dataclass
class A:
@attributes_from_signature
def __init
Yeah, I'm beginning to see that positional args are going to make it
unworkable. I'll write up another proposal with just normal args and
keyword-only args.
Thanks everyone for your feedback!

Good point. I'm not familiar with CPython internals so I'm not sure how
this would work on the implementation side, but I definitely think it would
be impor

If you feel so strongly about it maybe we need to see some credentials.
What's your background? (This may sound like an odd request, but reputation
matters, and right now I have no idea who you are or why I should take your
opinion seriously, no matter how eloquently it is stated.)

Hi Steve,
I don't think I can explain adequately why I challenged you, so I'll just
apologize. Your feedback (about the 'export' proposal, and about my
challenge of your credentials) is duly noted. Sorry!

I completely agree with this. One of the hallmarks of Python is the ability to
