Comment 7 for bug 391965

SUVersionComparision is a protocol, not a class. That basically invalidates all your comments.

And I don't think it makes sense to compare version numbers inconsistently. If a developer needs a different way to compare version number than this says something about the format of the version numbers he uses, and that is relevant for this situation just as well. It doesn't matter what YOU need, it matters what others can expect.
