      range: [start_number, end_number]       (where the numbers are indexes into the input string, regular zero-based)
    }
  
  
    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)
    }
