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

[thebluepandabear]

Something interesting.

I know that D has C++ SFML bindings, although they are 
unmaintained.

I was interested to see how they would 'implement' the C++ 
namespaces of SFML, and - boy was I surprised.

Reading through `DSFML`, I see `final abstract class` getting 
used to implement SFML's `Keyboard` namespace:

`final abstract class Keyboard` at 
https://github.com/Jebbs/DSFML/blob/master/src/dsfml/window/keyboard.d

It seems like using `final abstract` is the best solution.
