> However, by contrast, the core implementation of the `log()` function, as far as I'm aware, could not possibly be borrowed and reused against any random JS object in any useful way, 

Two problems:

- This isn't something special about console.  Calling Element.prototype.appendChild on something that isn't an Element, or Worker.prototype.terminate on something that isn't a Worker, doesn't make any more sense than calling console.log on something that isn't a console.  If we take "not useful to call on random objects" as a reason to do this, then we'll be doing it with tons of APIs--which is why we shouldn't.
- This isn't a reason why methods on other APIs aren't bound to their object.  After all, if you do want to call a method--say, appendChild--on an interface on something other than an instance of the object, you wouldn't say "document.appendChild.call(otherObject, node)", you get the method from the interface: "HTMLElement.prototype.appendChild.call(otherObject, node)".  Binding the functions wouldn't prevent this, but we still don't do it.

I'm running low on time and energy for this, and if the discussion so far hasn't convinced whoever in WebKit's process needs to be convinced, I don't think another five pages of discussion will help.  So, unless new information arises, I'll be winding down in this discussion for now.
