Kris Kowal: I'd like to see a proposal / document that outlines the minimum shared Module interface between expressions, instance imports, and virtualisation. I think this is:

class Module {
  get source(): %AbstractModuleSource%;
}

const mod: Module; // could come from expression, instance import, or constructor

await import(mod); // these modules are importable
new Worker(mod); // or usable as the entrypoint to a Worker
self.postMessage(mod); // and structuredClonable (transferrable) to other contexts

From there, we can pursue all three ways of getting ahold of a Module in parallel:

• expressions
• instance imports
• constructor (this one also introduces ModuleSource)
