I guess such a thing does not make sense in Common Lisp | but it plays a role e.g in Eiffel, Sather, C++ as a design tool. Let's see is the person requesting this can describe it well enough to be implementable or even desirable in Common Lisp. I'm not too interested in what it would mean in another language, but this is probably because I occasionally use English expressions in Norwegian and vice versa and thus know just how incredibly embarrassing it can be to forget which language one is using. #:Erik -- If this is not what you expected, please alter your expectations.
