This is interesting JEP to read: https://bugs.openjdk.java.net/browse/JDK-8280836 and I wonder what could be the consequences to Clojure?
probably not a lot in the short term
in some long future, maybe we'd implement these interfaces in the persistent colls where they make sense
java immutable records, java function interface, now java abstract sequences... waiting for the day that java will adopt lisp syntax too
