Project-Range expression fails inside macro for UDF arguments 
--------------------------------------------------------------

                 Key: PIG-2617
                 URL: https://issues.apache.org/jira/browse/PIG-2617
             Project: Pig
          Issue Type: Bug
          Components: parser
    Affects Versions: 0.9.2, 0.10
            Reporter: Doug Daniels


The Project-Range feature (fieldA..fieldB) fails inside a macro for UDF arguments, but works outside of a macro.

For example, this script works:

{code}
input_data = LOAD 'input_strings.txt' USING PigStorage('\t') AS (x:chararray, y:chararray);
output_data = FOREACH input_data GENERATE CONCAT(x..y);
{code}

but this script fails:

{code}
define my_macro(incoming) returns outgoing {
    $outgoing = FOREACH $incoming GENERATE CONCAT(x..y);
}

input_data = LOAD 'input_strings.txt' USING PigStorage('\t') AS (x:chararray, y:chararray);
output_data = my_macro(input_data);
{code}

with stack trace:
