I agree with you that, in most cases, bringing a language into a project established in another language is a bad idea. I do not, however, think that makes every high-level language exactly the same. Furthermore, I do not think that makes the currently selected language *always* "The Right Tool For The Job." Sure, sometimes it is a much better decision to use the "wrong" tool for the job... but that doesn't magically make it a better tool.

I guess the main difference boils down to how we're interpreting "The Right Tool For The Job." You are taking the more pragmatic approach, which I think is the right thing to do most of the time. I still think there's value in paying attention to the more abstract component, though. And that's what I think this whole Right Tool business is talking about.

In any case, I think we've flogged this freshly dead horse long enough. I guess I'll agree to accept your wrongful interpretation of this too-often used term. :)
