package child question

[Christoph Grein <christoph.grein@eurocopter.de>]

Matthew Heaney has pointed out the cause of your problem.

Apart from renaming, another solution is possible. Remember that any library
unit is supposed to be a child of Standard, so you might write

with A.B;
package body B.A is  -- this A hides the imported one

begin
   declare
      use Standard.A.B;  -- qualification makes it accessible again
   begin
      null;
   end;
end B.A;
