yes yes yes I know almost everyone can't stand this kind of naming style LoL ... you're welcome :)

The fact it requires this much explanation on how to declare a "best/proper" constant is not a great selling point for D. Sure, it is easy...once you know it and it reminds me of C++.

just renamed everything like following:

- sWhatever for structures
- iWhatever for interfaces
- cWhatever for classes

- udtWhatever for initialized structures
- objWhatever for instantiated classes

... far better ;D
