I just saw this post, which is essentially the same question as Basile Burg's. I hope that a college (in France?) is teaching D and that this is a homework assignment. Cool stuff! :)
Maybe using templates to create properties is a bit overkill in this example. But I could not solve what I thought would be a very simple and straightforward "template use-case" (initially I'm an embedded RT system C/asm developer).
I'm doing this for a personal project of a 3D engine. As I know little about C++/Java or other OO language, I thought I would do it directly in D, which seems very promising to me (but unfortunately not taught in France as far as I know).
