First note that I am not saying that your way is cluttered, but I prefer

with Ada.Text_IO;
with Ada.Integer_Text_IO;

use  Ada.Text_IO;
use  Ada.Integer_Text_IO;

because I like keeping the two in separate regions of my code and the lines
shorter.  Anyway I prefer that the context clause sticks because it helps
the readers familiarize themselves with the code base.  There is nothing
more annoying than jumping into a project's code and not being able to
figure out the main dependencies.  So in response to Russ's claim that
context clause are ugly lawn junk, I suggest he play around with visual
basic a little bit.  VB modules do not list their dependencies in the source
code so working on other people's code is a major pain.  Java is almost as
bad since import clauses are optional.  C headers are annoying to read due
to all the preprocessor crud embedded in them.  Give me context clauses and
package specifications any day.   They are more like having a well designed
landscape for a yard.
