Hello,
sub myfunc {
my @x=(1,2,3);
return \@x;
}
# or,
sub myfunc {
my @x=(1,2,3);
return [@x];
}
which one is the better way to return the list content? And if the
method is an instance method?
Thanks.

Since this is a shadow copy, I don't think the first array will be

The second option creates the same array and populates it, but then
copies it to another anonymous array, deletes the first array, and
returns a reference to the copy.
