Polyglot programming with Graal will eventually be awesome, but it isn't yet. If it was, I'd use Graal to use Python libraries from Clojure, but I'm not, because it still has some ways to go.

So for now, I use Pandas, Numpy, matplotlib, and all that from Clojure using libpython-clj. Which is the biggest issue with graal-python currently, how to leverage all the C-based libraries. That's where libpython-clj excels over Graal.

Yep and even then Clojure has Erlang and .net runtimes and interop built syntactically into the language, GraalVM has to reimplement those languages in it's tooling so they'll always be playing catch-up with the real implementations (unless they merge)

That said we do like GraalVM it has a cool ability to create native binaries out of Clojure apps, which is currently powering a resurgence in Clojure for scripting the last wave had to use Clojure's JavaScript target (cljs)

Yeah binding with C is a general JVM problem. Hopefully project Panama will solve that soon :)

What is your experience with python interop in clojure? Does it work sufficiently well that it is really usable or is it rather experimental?
