> ------------------------------------------------------------------------

> The below script when executed with version 0.9 fails with parsing error.
> {code}
> ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1000: Error during parsing.
> <line 2, column 15> mismatched input '{' expecting GENERATE
> {code}
> Script1
> {code}
> register myudf.jar;
> A = load 'test.txt' using PigStorage() as (a:int,b:chararray);
> B1 = foreach A {
> C = test.TOMAP('key1',$1)#'key1';
> generate C as C;
> }
> {code}
> The above happens when, in a nested foreach i refer to a map key directly
> from a udf result
> The same would work if one executes without the nested foreach.
> {code}
> register myudf.jar;
> A = load 'test.txt' using PigStorage() as (a:int,b:chararray);
> B1 = foreach A generate test.TOMAP('key1',$1)#'key1';
> dump B1;
> {code}
> Script1 works well with 0.8.
