 I took a quick look at this. I *can* get it shorter (or at least simpler) - the
 parser chokes when it encounters an assignment combined with method calls or
 field accesses.
 
 public class A
 {
   public int someint = 5;
 }
 
 public class Bar
 {
   public void bar ()
   {
     A a;
     A b = new A();
     int c;
 
     c = (a = b).someint;
   }
 }
