Well, a (lazy) seq has a value and a rest which is again a (lazy) seq. In your original code, you also added metadata to every seq the complete seq was built from, so it has been the very same overkill in principle. > Are there any other options I'm missing here? As you've said, you could add the prefix map to the triples. Or you could make you functions return tuples of the form [triple-seq prefix-map]. However, to build the complete prefix-map, you'd possibly need to parse everything, so the benefit of a lazy triple-seq is gone. So I think I'd just go with the approach of adding the prefix map to the triples. Since that's the very same map most of the time anyway, it's only adding one pointer per triple which is not so bad as it seems.
