Interesting. I'm suspecting we are going to see a lot of non-web use of wasm pretty soon.
I'm particularly interested in getting the AOT parts of LLVM, minus the optimization passes and other crufts, to compile wasm to machine code. A very slim wasm-to-machine-code backend.
It will be interesting to see a Node-like env for wasm, but without the JIT compiler since wasm is AOT-compiled anyway unless one is considering dynamic loading of wasm modules.
It would be spec-compliant and would allow all languages that target wasm to run on it.
