It's interesting reading your comment that purports to disagree with mine, while feeling that it instead agrees... I think perhaps the confusion is that I misread your comment that I replied to as suggesting that you can't have an executable spec, rather than (as I now think you meant) as merely claiming that an implementation can't be its own spec, which I definitely agree with.

I think something like RubySpec is fantastic, and that it's really too bad that, perhaps only because of personality conflicts with the maintainer, it hasn't been successful at standardizing behavior across ruby implementations.
