Examples

Executor e =...
e.execute {
   doSomething(a);
}
final int i = 1;//you still need final to access i in function
h.invoke(obj, () doSomethingWithIn(i));
Arrays.sort(array, (o1, o2) o1.hashCode() - o2.hashCode());

//Nested closure constructs are supported to some degree
interface Provider<T> {
  T get(Object context);
}

public Provider<Provider<Provider<String>>> myProvider() {
  return new Provider<Provider<Provider<String>>>() {
    public Provider<Provider<String>> get(Object c) {
      return new Provider<Provider<String>>() {
        public Provider<String> get(Object c) {
          return new Provider<String>() {
            public String get(Object c) {
              return "MyFavoriteStringFactory" + c;
            }
          };
        }
      };
    }
  };
}
//....
// Which may be collapsed to..
public Provider<Provider<Provider<String>>> myProvider() {
  return (c) (c) (c) "MyFavoriteStringFactory" + c;
}
