And the types will be recognized by type checkers such as mypy.
And I think the non-typed examples should go first in the docs.
I still don't understand why "I don't care" can be defined by "leaving out"
@dataclass
class C:
   b = 0.0 # float field with a default
For non-default fields, I like ellipsis too.
