In other words this code:
sub x {
();
}
@x = x();
use Data::Dumper; warn Dumper([\@x]);
shows that @x is bound to a list with one element.
No, it's not. Watch this:
sub routine { return (); }
@x = routine();
print 0+@x;
This prints 0, as expected. You are handing to
Data::Dumper a list
of one item, that one item being a reference to your empty array. Stop indirecting
so much!
