      Description

      Pig generates an error with this script:

      grunt> a = load 'a.txt';                      
      grunt> b = group a all;                       
      grunt> c = foreach b generate COUNT(a) as sum;
      grunt> d = limit a 1 * c.sum;  
      [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1200: <line 4, column 14>  mismatched input '*' expecting SEMI_COLON
      

      The reason is the parser chooses the wrong alternative.
