I don't get it. Furthermore according to

    https://wiki.dlang.org/Access_specifiers_and_visibility#private

there is always external linkage on private variables and 
functions.
Does D not provide a means to stop symbols from going into the 
object file?

You've declared `Private` as `package`.

Hit but not sunk. It makes no difference:

~~~Private.d
module Private;
import std.stdio: writeln;

class A {}
private class B {}
private class Private {
    void foo () { __PRETTY_FUNCTION__.writeln; }
}
~~~

$ dmd main.d
$ ./main
void Private.Private.foo()
