Here I would take inspiration from the Java world, where a "domain" is used per project. Typically this domain is written from the most general part of the domain to the most specific, so "web.example.com" becomes "com.example.web".

For example:
```
import org.springframework.boot.SpringApplication;
```

So you could have: com.alicorp.a, com.alicorp.b, and com.alicorp.c

That being said, D is not Java, thus things like the company top-level domain could be left out and you end up with alicorp.a, alicorp.b, etc.

Thus the problem of name collision goes away until someone else tries to take the name "alicorp". I believe this is why Java uses the full domain, because unique domain ownership is already a solved problem, they just ride along.

Packages like `vibe` follow a similar mechanism, where all the useful modules and packages are nested under a single package.
