This shouldn't work.  Comment #7 is solved simply by using bind(); calling a bound console function does work as expected (it may not have back in 2010, but it does today).

You can't pull random member functions off of objects and have it work.  You can't say "g = document.getElementById; g('foo')".  That's what bind() is for.

This might make a little sense if console.log acted like a static function (eg. if it didn't actually care about the console object), but it doesn't; which console.log you call determines which console it goes to.  Please don't add new weird things to the web.

Notice that WebIDL has a big angry red box explicitly warning against this.
