@phistuck pay attention to the arrow, the thin one does not bind the context at creation time. this would be the expected object in that method.

Wow, for some reason I got no notifications for this thread. Sorry all. @domenic is quite right. This was me looking at an experimental feature, and I was jumping the gun somewhat. Fat-arrows are only partially implemented in the version of V8 in that version of Canary and full support will come in time.

The two versions were not picked to be equivalent in terms of their development process. They just happened to be the browsers I was testing with.
