Right now we just throw an exception in a random place for these. I'm not sure what the right behavior for these in JS implemented WebIDL. I don't know if we want to just fail in a more useful manner, or if we want to implement them somehow.

Implementing these should not be too bad, I'd think. We just need to append the right methods to the "callback interface" part of the codegen, and then I think it should Just Work.
