I looked into the state of GraalVM and Clojure and wrote some small work-related scripts.

Downloaded GraalVM and set $GRAALVM_HOME
Found two main libraries for building GraalVM CLIs - https://github.com/luchiniatwork/cambada#packaging-as-a-native-image and https://github.com/taylorwood/clj.native-image (or https://github.com/taylorwood/lein-native-image for the lein equivalent). I chose clj.native-image as it seemed more focused on doing one thing well.
First tried its template example which was easy to follow.
Then added a graalvm build to one of our small cli tools
Found it to be pretty straightforward except for a stdout flushing issue that was trivial to fix

There is a way how to install V lang on Windows using Scoop installer. I prepared the manifest myself and put it to bucket maintained by me.

scoop bucket add scoop-littleli https://github.com/littleli/Scoop-littleli.git
scoop install vlang

There is also an option to bootstrap V lang using llvm-mingw which contains stable Clang. I successfully recompiled V lang with it.
