Is this possible in GraalVM?

(eval '(defmacro testing [] 123))
  (println (macroexpand '(testing)))
I'm getting

Currently running [org.clojure/clojure "1.10.2-alpha1"]

Sci does manage to do it. Not sure how though

borkdude13:08:43

Not possible in GraalVM. Sci works around it by being an interpreter.

kwrooijen13:08:05

Ahh ok, got it

kwrooijen13:08:37

I guess I could try to use sci in that case

kwrooijen13:08:40

Awesome, that works

kwrooijen13:08:47

Guess I'll be using Sci afterall 😛

I don’t think we talk about runtime evaluation in our clj-graal-docs, I’ll add a tip.

iirc the story behind babashka is intimately related to this point, a train ride and jet...or something
