: +      input instanceof CharStream ?
: +        (CharStream)input :
: +        new CharReader(input)

this seems like it might be a useful idiom to put in a static method of 
the CharStream class...

  public static CharStream get(Reader input) {
      return (input instanceof CharStream) ?
             (CharStream)input :
             new CharReader(input);
  }
