I did. It adds no value over and above what Ruby already has and
uses. You can say that the error messages will be better, but I
disagree. How is saying that "I expect a Socket" any better than
saying "I don't know how to deal with #accept"?

And *that*, Sean, is fundamentally why I disagree with this
proposal. It doesn't add value, and it makes promises that it can't
even come close to keeping.
