Clojurians Log v2

I guess it's expected that the non-inlined version of alength uses reflection, right?

well you don't care if it's inlined :)

maybe the inlined one does as well btw. it's the same.

user=> (. clojure.lang.RT (alength (into-array [1 2 3])))
Reflection warning, NO_SOURCE_PATH:1:1 - call to static method alength on clojure.lang.RT can't be resolved (argument types: unknown).
3

(ran into an issue with graalvm with this)

$ bb -e "(count (into-array [1 2 3]))"
3
$ bb -e "(alength (into-array [1 2 3]))"
----- Error --------------------------------------------------------------------
Type:     java.lang.ClassNotFoundException
Message:  clojure.lang.RT

Sort of amusing, because the jvm alength instruction doesn't care about the array type, so doesn't require reflection, but you can't write a java method that takes any array type (prims or objects), so RT has a bunch of static methods, alength could call any which introduces reflection

I don’t think so w how inlining works

Given the amount of time I’ve spent optimizing array code in bytecode with Clojure, I’m pretty sure I would have noticed that

Perhaps if it’s inlined, in a lot of cases local inference will take care of it?
