------------------------------
Status: Patch Available (was: Open)
Hey, [~alangates], I fix this issue by adding detecting logic when substitute
the macro arguments.
I also add another negative test case to catch this issue.
I run the whole TestMacroExpansion tests and it pass for me.
> Pig parser does not detect multiple arguments with the same name passed to
> macro
