No, it is not.  Constructors should not cause a struct to be considered non-POD
for extern(C++) functions.  I don't care what we do with extern(D) functions,
but we need to match the C++ compiler.

"If a C++ object has either a non-trivial copy constructor or a non-trivial
destructor [11], it is passed by invisible reference (the object is replaced in
the parameter list by a pointer that has class INTEGER)[12]"
