Not really the same, while in the same area, this topic make think about  
an old entry in my bookmarks, which may complete yours. A web paper about  
dimensional arithmetic in Ada
http://www.christ-usch-grein.homepage.t-online.de/Ada/Universe.html

Keep in mind it's a bit old, so this may need some review.
