What I really want.

gistfile1.java

private static abstract class MyClosure implements Runnable {
   MyClosure( int x ) {
      this.x = x;
   }
   int x;
}

/* later... somewhere in a method */
int x = 42;
handler.post( new MyClosure( x ) {
   public void run() {
      progress.setProgress( x );
   }
}

/* I want this: */
int x = 42;
handler.post( lambda() {
   progress.setProgress( x );
}
