I JUST was playing around with this.

I think an IUnknown class is implicitly extern(Windows) for all the methods.
You have to explicitly mark toString as extern(D).

Ah, thanks. I kept seeing people use extern(Windows): in their COM classes
and thought that was strange.

I'll update this so it becomes a documentation issue.
