curious hook

[hallenberg]

In group.php...


// Render bits
$mygroup_bits = '';
foreach ($mygroups AS $mygroup)
{
$mygroup = prepare_socialgroup($mygroup, true);
$mygroup['canleave'] = can_leave_group($mygroup);

($hook = vBulletinHook::fetch_hook('group_list_mygroupsbit' )) ? eval($hook) : false;

$templater = vB_Template::create('socialgroups_mygroups_bit');

$templater->register('mygroup', $mygroup);
$templater->register('template_hook', $template_hook);
$mygroup_bits .= $templater->render();
}


..I'd like to use that hook to make decisions about which template bit to use, and/or to 'continue' over the foreach.. In fact there are various places where I'd like to break or skip a loop from within a hook.

Lo, I can't.. Or can I?
