Multiple sumti link; open-ended sumti-linking.
Terminated by be'o. Until terminated, all following sumti are considered to successively fill the terbri (in order) of the selbri which immediately precedes this word, filling in accord with the order presented (overridden by FA), starting at x2 by default. In a sense, this word delves into the world of the selbri, treating it (temporarily/until terminated) as the selbri of a bridi. (This word reduces the number of be's and be'o's required, as well as reduces the amount of jumping around in an utterance/the thinking required.)
