I misunderstood what was being said then. In which case I agree with the 
contributer who thought up a whole pile of silly warnings. That could be
economised with a single one:
    warning: This language follows the documentation.
I have one concern. Don't break existing code. After that almost any change
can be considered and maybe implemented.
