Streams should use DOM4 style errors.

Is there a working group where we can send out comments about the spec?

[Adam Barth]

http://dom.spec.whatwg.org/#interface-domerror

Basically, the modern way to do errors is to use strings rather than numeric codes.  Also, you don't need to create a subclass for each features.  Instead, you just use DOMError directly.

[Adam Barth]

Take a look at how IndexedDB throws exceptions:

The maintainer is listed as [e-mail].  I'll send him an email, and modify my patch to match IndexedDB.
