That sounds right to me too.  You need a lot of machinery to make them explicit,
and it can only help when there are lots of duplicates.  Probably, if we *need* to
deal with duplicates, there’s a “softer” way to do it, such as using implicit IDs and
grouping the duplicate-branching cases with some other signal, such as an “I’m
with him” optional flag.
