Massimiliano,
An agnostic element doesn't need to use simple_action(). It can provide both
push() and pull() methods. The relevant method will get called, and you can
see the port that way. Check out the Suppressor element, which has pretty
much exactly this high-level spec. elements/standard/suppressor.{cc,hh}
