This is such a nonsense solution. Why do you keep proposing it?

Is this you way to effectively sweep the problem under the carpet?

For me, a module presents the opportunity to group objects into a 
larger working unit.

But since D does not respect the encapsulation of objects, one 
has to revert to your solution, or mine (which is, if you're 
solution to a problem requires the use of classes, then go use a 
progamming language that respects the encapsulation boundary of 
classes).
