I do wonder about the approach of defining an 'official' Ratfor or F that is strict subset that removes all the old parts of the language and doesn't worry about compatibility with the old code leaving only what is considered best practice. It might be very helpful to show folks the current way to do things while the full language is available to migrate code if it is considered cost effective. Plus, it would be helpful for go forward code. I wonder what a Rational C++ would look like with Concepts and the lot.
