I don't understand you. Are you arguing that we don't need `private`, or 
even visibility, at all, because we should just use interfaces?

Because otherwise, once you accept the need for `private`, then the 
question is what the limits should be.

D chose "module", which I can understand, but don't share, at least not 
as the only option. I think the class / scope is a much more natural 
boundary, as it is for visibility.
