I meant Clojure. Janet's "more default looking" data structures are the immutable ones which is a pretty strong nudge. I don't see any explicit callout about data sharing for Janet but if that's really all that's missing I still feel good about citing Clojure first.

Except they're not immutable in the clojure sense (of persistent data structures), they're just fozen / readonly, as can be seen from their complexity bounds (and the lack of transients). And a quick check didn't show any incompatibility between the two worlds either.
