> isn't that a double standard? Not at all. There's a big difference between saying "this version of MacRuby is good enough for this particular application", vs. "this version of MacRuby is good enough for all applications". Once it's added as a public framework to the OS then Apple is committed to maintaining the framework's security, stability, and backward compatibility in perpetuity, or at least for a very long time. OS and platform vendors never make those decisions lightly. It is an encouraging sign that MacRuby is at a point where Apple is comfortable using it their some of their code.
