I am just hopelessly confused on how to achieve the same in D.
Uncharitably: D is a friendless language. Charitably: D is so
much more friendly that instead of a short explicit list of
friends, D has a large implicit list of friends: everything
else in a module.
That's why this works:
```d
class Secret {
private int id;
}
void main() {
import std.stdio : writeln;
auto s = new Secret;
writeln("visible to me: ", s.id);
}
```
But this doesn't:
```d
void main() {
import std.stdio : writeln;
import secret : Secret;
auto s = new Secret;
writeln("visible to me: ", s.id);
}
```
Error: no property `id` for type `secret.Secret`
I'm sorry, I should've explicitly mentioned I'm interested in
learning how to do friend injection in D.
I know that access specifiers operate at module scope, seen a
few posts about that here already.
Thank you for answering though.
