lld-link: error: subsystem must be defined
Error: linker exited with status 1

Is this intended?

It's not a problem to add temporary
```
void main() {

}
```
to the bottom of the module, but seems wrong as not then testing 
_exactly_ what is to be imported elsewhere.

You can add the `-main` flag to make dmd automatically add such 
an empty main function when there isn't a `main` already.
