But what about `tupleof`? It ignores `private` and it's allowed in `@safe` code:

Now that I've sent this, I find the affected Phobos type I couldn't pinpoint. It's `File`:

void main() @safe

    import std.stdio: File, writeln;
    auto hosts = File("/etc/hosts");
    {
        auto hosts_copy = hosts;
        hosts_copy.tupleof[0].refs = 1; /* uh-oh */
    }
    auto self = File(__FILE__);
    writeln(hosts.rawRead(new char[1000]));
        /* Reads from __FILE__ instead of /etc/hosts. */
}
