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
}
```
