It is not *much* different, just more Catalyst-ish.
before and after are most likely placeholders and will be replaced  
later,
you will be able to overload individual steps like validation and  
subclass other reusable actions.

Controller base classes are supposed to contain multiple actions,  
while "reusable actions" are just single actions.

DefaultEnd is a plugin, and can be converted to a reusable action class.


     package Catalyst::Action::Add;

     use base 'Catalyst::Action';

     sub do_stuff {
         my ( $self, $c ) = @_;

         # add new record to model

     }

     1;



     package Catalyst::Action::Add::WithValidation;

     use base 'Catalyst::Action::Add';

     sub validate {
         my ( $self, $c ) = @_;

         # validate params

     }

     1;


MOOSE!!!
