Base classes affect the whole controller, reusable components just  
the action.

     package MyApp::Controller::Foo;
     use base 'Catalyst::Controller';

     sub add : Local : Action('Add') {}

     sub del : Local : Action('Del') {}

IMO the above example is easier to understand and maintain than the  
following.
(Especially when your Controller contains 20 or more actions,
which may all inherit something from a reusable action)

     package MyApp::Controller::Foo;
     use base qw/Catalyst::Controller GenericAdd GenericDel/;
     use NEXT;

     sub add : Local {
         my ( $self, $c, @args ) = @_;
         $self->NEXT::add( $c, @args );
     }

     sub del : Local {
         my ( $self, $c, @args ) = @_;
         $self->NEXT::del( $c, @args );
     }
