Looking at the GC code found @ 
https://github.com/dlang/dmd/blob/master/druntime/src/core/memory.d, it seems like they have disabled the default constructor:

```D
struct GC
{
     @disable this();
     ...
}
```

Interesting, so maybe there is a use case for a purely static 
type or namespace?

The standard library as well uses `final abstract class` a couple 
of times, which can also be thought as a type of namespace.

All these 'hacks' to workaround a namespace-like feature are ... 
interesting... So maybe such a feature would help the language?

Just askin questions!
