I believed that your private parts were hidden in Ada.
Though, the function Bs.Something manages to call
As.As_Private_Parts though it is a private type
with a private procedure in the short example below.
package As is
type A is private;
private
type A is tagged null record;
procedure As_Private_Parts (An_A : in out A);
end As;
with As;
package Bs is
type B is new As.A;
procedure Something (A_B : in out B);
end Bs;
package body Bs is
procedure Something (A_B : in out B) is
begin
As_Private_Parts(A_B);
end Something;
end Bs;
Compiling bs.adb does not report any error - how can that be?
Should B be allowed to see A's private parts?
Is it a feature or a bug?

Excuse me, that type of language is no longer allowed on the Internet
because of the US's recently-passed Communications Decency Act. Clean
up your language or this newsgroup will be voted out by the US
Congress.

Big smiley, for those of you that actually thought I was serious :-)

Sounds like a bug. (In the compiler, not the language.)
