Important: This is slower and less scalable than BiConstraintStream.join(UniConstraintStream, TriJoiner)
with a proper TriJoiner
predicate (such as Joiners.equal(BiFunction, Function)
,
because the latter applies hashing and/or indexing, so it doesn't create every combination just to filter it out.
