You can convert it to Kotlin and just use LLVM-based native[1] compilation that is even more complex efficient. It's completely automated, and gives you the better and more modern language without much hassle.

Except it barely has a stdlib without the JVM. You cant even read a file in knative without having to do a posix syscall.

It actually produced somewhat slow code and has an awkward memory model without shared memory multithreading.
