There are plenty of comments about converting the entire Julia process into a WASM process, but is there any way to load and execute WASM IR in a julia environment.  
I’m looking to develop a function in Rust, convert to wasm IR. Then use this function in Julia. Seems like it should be do-able.

I think you’d need a whole WASI runtime and implement an `Embedder` for Julia. Not impossible, but not trivial. Probably easier to target LLVM IR and then use Julia’s inline LLVM to call it? Or easier yet to just compile a binary with a C header and use `@ccall`?
