Yes -- you can do:

 my ( $class, $method ) = $R->lookup_action( 'action_name' );
 $class->handler({ task => 'create' });

or if you'd prefer calling it directly:

 $class->$method();

You can see an example of this in OpenInteract::Handler::Logout in the
'base' package where we do:

 my ( $action_class, $action_method ) = $R->lookup_action( 'redirect' );
 return $action_class->$action_method({ url => $return });

This will be replaced in the relatively near future by an actual
action dispatcher, where you'd simply do something like:

 $R->dispatch( 'action_name', \%params );

And have security get checked properly, parameters from the action be
passed into the action, etc.
