Is there a difference to
sub myfunc {
return ( 1, 2, 3 );
}
? And my understanding was/is that in
sub myfunc {
my @x=(1,2,3);
return \@x;
}
a reference would be returned to an array that ceases to exist when the
function returning it has finished. At the point the function returns
to, there isn't anything left the reference could refer to.
Or is there?
