New submission from Christodoulos Tsoulloftas <ch...@komposta.net>:
I am trying the new slots directive but I get an AttributeError when I try to
access a field with init=False
>>> from dataclasses import dataclass, field
>>>
>>> @dataclass(slots=True)
... class Example:
... a: str
... b: str = field(default="b", init=False)
...
>>> obj = Example("a")
>>> obj.__slots__
('a', 'b')
>>> obj.
obj.a obj.b
>>> obj.a
'a'
>>> obj.b
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: b. Did you mean: 'b'?
>>>
