Hi All - FYI, Cameron updated his Web IDL tests and they can be reviewed 
and run directly via the following, respectively:

* <https://github.com/w3c/web-platform-tests/pull/271>


Getting review of these tests is important so any help (even if you only 
review a subset of the tests) will be greatly appreciated.

-Thanks, AB
