          Issue ID: 12734
           Summary: Template cannot deduce E[] from typeof(null)
           Product: D
           Version: D2
          Hardware: All
                OS: All

-----
void take1(int[] buffer) { }
void take2(E)(E[] buffer) { }

void main()
{
    take1(null);  // ok
    take2(null);  // fail
}

I'm not sure what 'E' would be deduced to with a typeof(null) though. Maybe
just a 'void'? Or a 'void*'? It's hard to tell, but the above forces us to
create overloads for the sake of supporting null.
