sub x {
    undef my @x;

#   return (@x ? @x : ());

@y = x();

!defined(@y) && warn "y not defined";

How can I return an empty list instead of an undefined value from x()? In other words, if the results of x() result in its local @x being bound to () or undef, then I want to return an empty list.
