If one were able to define such a method in a class that overloaded +. I
don't know of an example in Java where one could.

public class SideEffect {
public static void main(String[] args) {
Object o = new SideEffect();
System.out.print("Hello, ");
String someString = "X" + o;
System.out.println("World");
}
public String toString(){
System.exit(3);
return null;
}
}
toString does overload part of the functionality of "+", the string
conversion step when one operand is a string and the other is a
reference expression.
