Right, but that's kind of my point. Adding it to the language spec now creates an additional and frankly somewhat unnecessary point of compliance for other implementations. Python is already so damn big and complicated, my opinion is that we shouldn't makes its spec even more complicated, even if its reference implementation adds more features like this.
