As far as I'm aware, released versions of Opera do not have full
support for ES5. E.g.,
data:text/html,<!doctype html><script>alert("keys" in Object)</script>
alerts "false" in Opera 11.50 (although "true" in recent
Chrome/Firefox), and "Check For Updates" tells me this is the latest
version. Object.keys is defined in ES5:
http://es5.github.com/#x15.2.3.14
I don't object to using any features that are supported by the latest
version of every major browser. I already do so in my tests, so it
won't affect me if testharness.js does too.
