I wonder if GraalVM would be a good addition as a new target for Haxe?
If the Truffle Language Implementation Framework is used, the Haxe code can be implemented to run in GraalVM. ( Truffle Language Implementation Framework)
This would allow Python, JS, Java libraries to be used directly at the same time in Haxe .
Also this would allow to compile directly to native with Native Image, for Windows, Linux, Android and iOS ( Building Multiplatform Mobile Apps With GraalVM Native Image ) for mobile development.
