   Your program fragment is well defined.   
      
   What the poster certainly tried to express was that in case you   
   haven't implemented a complete list of all possible cases and   
   also not provided a 'default' to catch all non-specified cases,   
   then you might get in troubles with your program, probably by   
   possible oversights, future extensions, new data, and whatnot.   
      
   Personally I have the habit to always define a default branch,   
   and even if that default is impossible to reach you'll find an   
   error message (like "internal error with unexpected value...")   
   generated at that place.
