You misunderstood.

In my code I write:

with Ada.Text_IO; \au

The \au which is my shortcut (it could have been Ctrl-J or F4 etc...
depending on preference) will then make this line look like:

with Ada.Text_IO; use Ada.Text_IO;

and I can continue typing. 

It will work with any withed package as it simply copies what comes
after with until the ;. A shortcut \aU removes the use Package; from a
line.

There is no preprosessors involded. As I have said: the convenience of
the writer is the responsibility of the text editor (in my case vim) not
Ada.

As to telling the reader which packages are used, the source code will
say so and you cannot manage to make it much clearer IMHO.
