[New-bugs-announce] [issue33539] Remove `init` flag from @dataclass?

[Barry A. Warsaw]

New submission from Barry A. Warsaw <barry at python.org>:

In reading over the new dataclasses documentation, I'm unsure what the `init` flag is used for, given that:

* If you already have a __init__(), then dataclasses won't add one
* If you don't have a __init__(), why wouldn't you want dataclasses to add one?  Without that, how do your attributes get initialized?

If there is a valid use case for `init`, I'm happy to add it to the documentation.  If there isn't, can we call YAGNI and remove the flag?

I'm mildly of the same opinion with `repr` but I can see some value in wanting to defer to object.__repr__().  OTOH, it should be pretty easy to just write:

@dataclass
class Foo:
    def __repr__(self):
        return super.__repr__()
