As I wrote, it has some pitfalls. In my blog I noted down the order of 
resolution, which is the way one would expect it to be in Java, analog 
to using inner classes. This is a variant using an instance 
initialization block (legal Java code):

String string = new StringBuilder() {{
   append(person.getName());
   if (person.isMarried()) {
     append("(married)");
   }
}}.toString();

As I, too, stated ;)
