@jeaye has put together a great test suite to test his and other Clojure dialects (bb among others) against JVM Clojure's behavior. you can help out with this test suite project by watching issues and responding to PRs or making new tests yourself. https://github.com/jank-lang/clojure-test-suite/issues/1 two issues were found recently around hierarchies: • https://github.com/babashka/babashka/issues/1893 • https://github.com/babashka/babashka/issues/1893 These issues were posted in babashka, but probably also relate to SCI. Feel free to look into those as well if you're interested.
