Perhaps something like:

```
class Foo
{
     private class string _id; // Private to the class
}
```

```
class Foo
{
     private module string _id; // Private to the module
     private int _number; // Same as "private module" since that's 
the default
}
```

Of course an equivalent to structs "private struct" could be 
added as well.
