while i'm at it: i've now implemented
const CARD* find_card(string name, CARD_LIST* Scope, bool nondevice=0);
in LANGUAGE as follows.

const CARD* LANGUAGE::find_card(string name, CARD_LIST* Scope, bool nondevice) {
  if (!Scope) Scope = &CARD_LIST::card_list;
  CARD_LIST::const_iterator i = Scope->find_(name);
  if(nondevice){
    while (i!=Scope->end()) {
      if((*i)->is_device()){ untested();
        i = Scope->find_again(name, ++i); // skip
      } else {
        break;
      }
    }
  }
  if (i == Scope->end()) {
    throw Exception_Cant_Find(name, "scope");
  }
  return *i;
}

i've changed the find_ call in LANGUAGE::find_proto to
try {
	p = find_card( Name, &CARD_LIST::card_list, !OPT::bogus );
} catch(Exception_Cant_Find) {
	assert(!p);
}

if there's really a language that does conditional bogus instanciations,
nondevice needs to be changed to prefer_nondevice... i'll leave it like
this for now.

have fun
