If currently available compilers came with cross reference listers, it would not be a problem reading listings that use "use" clauses. Lacking this, our project had a "do not use 'use'" rule. In a number of places, we did use the "renames" facility to be able to use operators in the normal manner (X := A + B). We also used the same facility to shorten names. Everyone who came to me with the question of "how do I get operators?" was upset about the need to write a "renames" statement for each operator. However, tracing problems to the correct package was made much easier than if "use" had been used (from experience on another program). Without tools, Ada(r) is a pain to write, but a joy to debug. With appropriate tools, the pain can be diminished. I also agree with everyone else that "use" clauses and "renames" should be used at the lowest possible level. -------
