It would be nice to have an example that works with WebAssembly. We should also have some tests that run a WebAssembly executable.
Some of the existing examples might actually work but it would still be nice to document this.

• Find/Write an example that works with wasm
  • Run this example with a wasm runtime
• Documentation
  • What does work with WebAssembly
  • Differences between wasm-unknown-unknown and wasm-wasip1
  • Differences no_std and wasm
