I would say that it's similar to #64928, but unlike #62894. Essentially, normal arrays (and hashes) are always defined in Perl 6. Even when they're empty, they're defined. Even when they've only been declared but not-yet-assigned to, they're defined. At least that's how I understand their semantics. In other words, this is one of a number of differences between Perl 5 and Perl 6, and the way Rakudo currently works is correct. Marking the ticket as rejected.
