I don't want to spread misinformation, it is actually used.
In dmd the classes have tag values so one does not have to do 
dynamic casts.
Tnone is used as tag for template parameter types which have been

It even has a mangle, but I doubt you should ever see it anywhere.
I will clarify with Walter.
