I don't believe the failing code uses opAssign. I believe that is 
initialization. In D2 "Num a = 1;" would be initialization or call a 
constructor if appropriate and "Num a; a = 1;" would use opAssign. Based on 
http://www.digitalmars.com/d/1.0/struct.html I am thinking it does the same 
(minus the constructors). So I think this might be a bug with struct 
initialization in D1, I don't think you should be able to just assign 1 to 
it.
