Perhaps the check could be:

  (type(lhs) == type(rhs) or fields(lhs) == fields(rhs)) and all

I think the types should *always* have to match, or at least
one should be a subclass of the other. Consider:

@dataclass
class Point3d:
    x: float
    y: float
    z: float

@dataclass
class Vector3d:
    x: float
    y: float
    z: float

Points and vectors are different things, and they should never
compare equal, even if they have the same field names and values.
