This change may break existing SAQL code. Update existing code to use this new behavior.

The second statement filters everything and returns empty results:
a = load "0Fbxx000000002qCAA/0Fcxx000000002WCAQ";
a = filter a by Year in [];
c = group a by ('Year', 'Name');
d = foreach c generate 'Name' as 'group::AName', 'Year' as 'group::Year', sum(accounts::Revenue) as 'sRev';
