Actually, no, you didn't. You provided a method to define
the meaning of the operator spelled '==' when applied to your
object. That's the level of abstraction at which Python's
__xxx__ methods work. They don't make any semantic assumptions.

It's arguable that there should perhaps be some default
assumptions made, but the Python developers seem to have
done the Simplest Thing That Could Possibly Work, which
isn't entirely unreasonable.
