Two things: one, C#'s generics are far less powerful than templates, and 
don't have all the issues that D's templates have.  It's probably much 
easier to detect this at declaration time in C# than in D.  Additionally 
generics are second-class -- the class owns the generic in C#, rather than 
the other way around.

Two, you _will_ get a compile time error message in D -- just as long as you 
instantiate the class template at least once, like C!(int) c;.
