   knows where the various procedures are declared.  Why can't it give us a
   cross-reference listing at the end of each compilation?  

   ... Saying "Don't use 'use'" tells me a lot about a project.  It is not using
   a sufficient APSE.  It has people who complain about Ada, since they 
   probably have difficulty reading their code.  And they are probably behind
   schedule, for similar reasons.

I agree to some extent. A good APSE is essential. On the other hand,
many features of Ada are for the purpose of encouraging
maintainablity, so why not add one more, if it's not too hard? Any
APSE tool is bound to be (slightly) harder to use than an editor, so
having readable source code is a good start.
