How do I instanciate multiple wasm modules generated using wasm-bindgen?

We’re using --target web, which generates a js wrapper code, which exports an “init” function using export default.

The first line of that init function is:

if (wasm !== undefined) return wasm;

If wasm is undefined, it will instanciate the wasm module, then set wasm = wasm.exports, which it appears to return.

If I’d like to start fresh, how would I do that, while keeping the convenient wrapper code?
