Example:

   for(String s : new Scanner("Scan this string")) {
      // Compiletime error, because Scanner is an Iterator but not Iterable
   }

   for(String s : new IterableForIterator<String>(new Scanner("Scan this string"))) {
     // works fine
   }

   or shorter (with automatic type deduction)
   for (String s : IterableForIterator.get(new Scanner("Scan this string"))) {
     // works fine
   }
