Non-ugly ways to implement a 'static' class or namespace?

Hi,

In Java/C# you can create purely static classes.

These are classes whose methods are all static, the classes 
cannot be derived from or instantiated:

```
static class Algo {
     void drawLine(Canvas c, Pos from, Pos to) { ...... };
}
```

Class in use:

```
Algo.drawLine(new Canvas(), new Pos(5, 3), new Pos(7, 9));
```

This type of semantics is not possible in D, which sucks.

After scouring the forums, the only workaround seems to be the 
following:

```
final abstract class Algo {
     void drawLine(Canvas c, Pos from, Pos to) { ...... };
}
```

This solution seems like a bit of a hack, which is why I don't 
like it.

Alternatively you could create a module, but then it would just 
be a function without a clear type.

Is anyone aware of a non-ugly way to implement a 'static' class 
or namespace?
