I think that particular issue was addressed in the recent Clojure release [https://clojure.org/news/2024/09/05/clojure-1-12-0] ("Clojure developers can now invoke Java methods taking functional interfaces by passing functions with matching arity.")

Looks like you're right! I stand corrected, it's admittedly been a few months since I've touched Clojure.

You were not wrong though, Java 8 was released in 2014, so it only took them ~10 years ;)

Yeah, and most of my professional Clojure experience was from 2018 to 2021, and a few personal projects in 2022 and 2023, and that lack of support for the functional APIs really annoyed me; I was writing a Kafka Streams application, which uses lots of lambdas, and it annoyed me enough to rewrite it with vanilla Java.

I'm sure it's a difficult thing to implement, so I'm a little forgiving, but considering that Java interop is one of the biggest selling points for Clojure I do think it's fair to criticize a bad experience with it.

I need to play with the newer stuff though; the linked changes seem cool as hell.
