Having a "readonly" class where the properties are read-only by default makes
sense to me, but maybe the better way to do it is with an attribute?
#[Readonly]
class Entity {
public int $count;
public string $data;
}
OTOH, that would be inconsistent with using `readonly` as a keyword for
properties.

P.S. Maybe readonly properties should be implemented with an attribute instead
of a keyword? But then that would be opening a can of worms...
