I have tried a few things here.  I can get this to work:


    for my $element (@{$myalums}) {
        $c->log->debug("alum:". $element->alumni_id);
    }


but not :

    while (my $alum =3D @{$myalums}->next) {
        $c->log->debug("id: ". $alum->alumni_id);
    }

In this case I get:

Can't call method "next" without a package or object reference



I'm assuming I'm just doing something obviously wrong here?

Thanks!
John
