Are there any plans to support WebAssembly?

I'm not sure what the best approach might be for WebAssembly. Can a WebAssembly module run code at startup?

Happy to take contributions!

@mmastrac Yes, Wasm can define a start section that points at a function index, and it's supposed to be invoked automatically upon module instantiation as defined here: https://webassembly.github.io/spec/core/syntax/modules.html#syntax-start

From what I know there's an ongoing debate on the rust core and how to approach this best as rust is 'no life before main' and the start section violates that. If there's any way to deal with this with linker magic, that'd be great.
