> 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
