   So is a multi-alternative case, as provided by Ada:

      case Foo is
         when 1 | 3 | 5 =>
            statement1;
         when 2 | 4 | 6 =>
            statement2;
         when others =>
            statement3;
      end case;

   The difference is that Ada takes care of exiting the case statement
   for you, whereas C requires (unsafely) that you use a break to avoid 
   being sucked into the code associated with subsequent cases.
