It can, yes.

The `==` operator is going to end up calling the `__eq__` method
defined just above anyway, and we're already in the implementation
details of `__ne__`.

So it felt more natural to me to have `__ne__` be the opposite of
`__eq__` rather than the opposite of `==`.

Also, `not (… == …)` feels weird, it screams "replace me by `… != …`".
Which I'm worried someone not paying attention might do in the future.

I don't feel very strongly about it though, so I'll change it if you
