Given
public abstract class Property<T> implements __<Property.µ, T> {
public enum µ {}
Property() {}
interface Cases<T, R> {
R Simple(Class<T> ownerClass
, String name
, Value value
, List<Param> params);
R Multi(Class<T> ownerClass
, String name
, List<Value> values
, List<Param> params);
}
public abstract <R> R match(Cases<T, R> cases);
}
we obtain
public static <T> Ord<Property<T>> propertyOrd() {
Ord<Property<T>> _propertyOrd = propertyOrd;

Ord<List<Property.Value>> listOrd = Ord.listOrd(_PropVal.valueOrd());
propertyOrd = _propertyOrd = Ord.ordDef(property1 -> property1.match(cases(
