Review Comment:
It's not possible to set the value of `EqaulOptions` in `== `or `!=`
operations, or alternatively, we could use default value for `EqaulOptions`
in those operations — but I think that would be a bit misleading. It's better
to remove `== `and` != `altogether so that users realize they need to
explicitly configure certain options for comparison
