We do have this handy dandy little assumption in our design however:

``foo\bar.d(1): Error: package name 'foo' conflicts with usage as a 
module name in file foo.d``

```
.
├── entry.d
├── foo
│   └── bar.d
└── foo.d
```

It does mean we can place multiple modules in a file as long as only one 
of them is the root.

```d
module root;

module root.foo {

}
```
