  the parseError function receives a 'hash' object with these members for lexer and parser errors: {
    text:        (matched text)
    token:       (the produced terminal token, if any)
    line:        (yylineno)
  }
  while parser (grammar) errors will also provide these members, i.e. parser errors deliver a superset of attributes: {
    loc:         (yylloc)
    expected:    (string describing the set of expected tokens)
    recoverable: (boolean: TRUE when the parser has a error recovery rule available for this particular error)
