Another use case for this is when you want a namespace inside a 
module with other top-level declarations. This is actually done 
for `core.memory` with a hack. There is a `struct GC` with 
`@disable this();` and only static members:
https://dlang.org/phobos/core_memory.html#.GC

It would be much nicer for the docs and code if an inner module 
could be used instead:

```d
module core.memory;
...
module GC
{
   nothrow void enable();
   nothrow void disable();
   ...
}
```
