Set packing only influences the number of bytes occupied by sets, not their
internal layout. And I don't think that should change, because they

Yes! Let's also convert integers to enums with a case statement rather
than typecast, just in case

This has never been allowed. The only thing that was allowed was defining an
enum as a default va

Is this intended behaviour ? I really hope it is not.
I cannot define the type of t
