I think that the other way round, Go on the JVM, might be nice. It could actually be faster than native Go; Go function dispatch might benefit from the HotSpot JIT inlining optimizations.
Why? I must be missing the connection between Node and Go.
For 15 minutes of fame on HN, of course.
Considering Go is slower than C, and the JVM is written in C/C++, I'd say the JVM would be slower.
I'm not trying to say I wouldn't like to see it, but I don't think anyone would use it, is all. And it's sad when cool software doesn't get used.
Once the JVM emits machine code for the bytecode, it doesn't matter what language the JVM is coded in.
