I thought the task is assigned to myself at the teleconference before F2F?
Also I would like to sit on examples for few more days to cover all the
corner cases before I start writing a comprehensive PR.

The examples on our issue tracker are just rough sketches. So please
understand mistakes and inconsistencies in the snippets. More importantly,
we still have (somewhat crucial) unresolved issues:

- Static resource loading: I've been sitting on this idea for a while, but
I am inclined to punt this to V2.
- AudioParam initialization: I think we're getting close on this one, but I
heard TC39 is planning to introduce 'static property' in class syntax, so I
want to check it out.
- Multiple node definitions in a single file: this allows developers to use
a hacky way of inter-node communication by sharing an object.

Once we settle on these, the next step is to create actual usage examples
based on the proposed IDL. I believe we can create a PR after that step is
