The registry also provides nice methods for checking if something has already
been loaded. Thats what I use it for
if (!Zend_Registry::isRegistered('somevar')) {
//do some processing
Zend_Registry::set('somevar', $value);
} else {
$value = Zend_Registry::get('somevar');
}
This helps a lot to store expensive things that could be getting called in
loads of different places.
