Hmm,
It does make you wonder if using the presence of an annotation to indicate
a field was a good choice -- but here we are.
Additionally one could consider adding an `attribute` typing construct,

Better yet, a dataclasses.attribute object that would indicate that:
from dataclasses import dataclass, field, attribute
@dataclass
class C:
x: int = 0
mylist: list[int] = field(default_factory=list)
y: int = attribute(value=0)
x and mylist are fields, y is not. y would get set to the value specified.
Then the type annotation is left unadulterated -- much easier for the type
checkers.
