ow with the default reduce entry.  While this 
      may sound dangerous, if not down right incorrect, it turns out that this 
      does not affect the correctness of the parser.  In particular, some
      changes of this type are inherent in LALR parsers (when compared to 
      canonical LR parsers), and the resulting parsers will still never 
      read past the first token at which the error could be detected.
      The parser can, however, make extra erroneous reduces before detecting
      the error,
