Hi all,

as you know, one of the tools that we have for testing is idlharness. 
What it does is basically that it processes some WebIDL, is given some 
objects that correspond to it, and it tests them for a bunch of pesky 
aspects that one should not have to test by hand.

One of the issues with idlharness is that it has long been based on 
webidl.js which was a quick and dirty WebIDL parser that I'd written 
because I needed it for a project that petered out. This meant that it 
increasingly didn't support newer constructs in WebIDL that are now in 
common use.

In order to remedy this, I have now made an updated version of 
idlharness that uses webidl2.js, a much better parser that is believed 
to be rather complete and correct (at least, it tests well against the 
WebIDL tests that we have). The newer webidl2.js does bring as much 
backwards compatibility with webidl.js as possible, but in a number of 
cases that simply wasn't possible (because WebIDL has changed too much 
to fit well into the previous model, and also because mistakes were made 
with it).

You can find the updated version of idlharness in this branch:

     https://github.com/w3c/testharness.js/tree/webidl2

The reason I'm prodding you is that idlharness, ironically enough, does 
not have a test suite. Because of that, I can't be entirely comfortable 
that the updated version works well and doesn't break existing usage. 
I've tested it with some existing content (e.g. 
http://berjon.com/tmp/geotest/) but that's no guarantee.

So if you've been using idlharness, I'd like to hear about it. If you 
could give the new version a ride to see if you get the same results 
it'd be lovely. Once I hear back from enough people that it works (or if 
no one says anything) I'll merge the changes to the master branch.

Thanks!
