Hello Brian,

Thank you for thinking on this feature. I want to better understand the
thought process behind marking all fields that are part of the component
state instead of only the derived fields. Something like this:

```

class Point(int x, int y) {
     private final int x;
     private final int y;
     private final derived double norm;

     Point {
         norm = Math.hypot(x, y);
     }

     public double norm() { return norm; }

     // derived implementation of x and y accessors
     // derived implementation of equals, hashCode, toString
}
```
