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'?
>>>
