What is the expose format?

[domenic]

That is, why is it

expose: {
  Window: { Node: Node }
}

instead of

expose: ["Window"]

and then we know the thing to expose is the interface export, and then name to expose is interface.name?

[Sebmaster]

This is intended for stuff like ImageHTMLElement, which is also exposed as Image.

[domenic]

It's not though. window.HTMLImageElement !== window.Image. window.Image is a useful factory function, whereas window.HTMLImageElement throws.

[Sebmaster]

Right, I had hoped that this would be somehow possible, maybe my having an expose prop on the impl export which can add more stuff to the global?

[domenic]

Hmm, I see, that makes sense. So in the future we'll do something like

expose: {
  Window: {
    HTMLImageElement: HTMLImageElement,
    Image: Image
  }
}

where Image is a generated wrapper that calls into something like implModule.namedConstructor_Image or similar.

[domenic]

Well, I'm not sure about the generated wrapper part (seems like a recipe for circular dependencies, since namedConstructor_Image would need to use one of the create functions from the generated wrapper). But the general idea makes sense. So let me close this and update #60.
