Yes, it seems like seperating chunks of C++ code into seperate 
modules and using the
```d
package(qualifiedIdentifier)
```
access specifier seems to be the way to go.

Was wondering if there was some wizardry that the veterans knew 
that would make it less difficult, but it seems this is the only 
way.

Thank you very much for replying!
