The specification technique (that was only sketched in my talk) is not
restricted to visibility, but allows as well to specify e.g. overloading
resolution and similar identification problems.


And the technique is much more general than needed for declare-before-use
languages, in particular free declaration order is no problem. The
question was whether it works for languages where no or multiple
declarations of a program entity are allowed. The answer is yes, but in
some cases not as natural as one can imagine.
