Hah, I wrote that code on the fly and didn't check the aforementioned test implementation, where I had `(a is None) ^ (b is None)` like the other commenter suggested.

You could just write this as

    (a is None) is not (b is None)

or

    (a is None) != (b is None)

It won't make a difference (and is 1 to to 5 characters longer), but it seems "cleaner" since it's more specific.
