As of Rakudo commit a9a9e1c97 neither t/spec/S03-metaops/zip.t nor the examples in this ticket actually using Z fail.  The code snippet showing the conversion of nqp::null to Mu has not changed behavior, but considering this ticket is about zip and not NQP difference between moar and jvm I am not sure that qualifies as a reason to keep it open, and I'd request closing.
