Yes, I know the RFC, it's a great piece of work! The use of interfaces
as mentioned in this RFC is however completely different from what
Pierre and I are talking about. If I understand Pierre correctly, that
is. The suggestion to include interfaces simply meant to allow freedom
of choice. Choice between using an operator (`==`) or calling the
equivalent method on the object (`->equals()`). That may get more people
on board with operator overloading.
