You can return as many structures as you want:

my ($hashref, $arrayref, @array) = new();
print $hashref->{'a'};
print $array[0];
print $arrayref->[1];

sub new {
    my $hashref = {'a' => '1'};
    my @array = (2,3);
    my $arrayref = [4,5];
    return ($hashref, $arrayref, @array);
}

You just have to be careful how you return them. An array is returned as a list of items, for instance, and Perl can't figure out where the list ends if you don't pass the array last:

## $arrayref isn't defined!
my ($hashref, @array, $arrayref) = new();
print $hashref->{'a'};
print $array[0];
print $arrayref->[1];

sub new {
    my $hashref = {'a' => '1'};
    my @array = (2,3);
    my $arrayref = [4,5];
    return ($hashref, @array, $arrayref);
}

For this reason, it's generally safer to pass arrays only via reference. Passing via reference is more efficient anyway, especially when working with large arrays.
