Also keep in mind that D supports other types than C does, like D 
arrays and delegates. In those cases the D calling convention 
needs to be extended since there's no way to just relay on the C 
calling convention. One could think it would be possible to 
passes D arrays and delegates as structs, but that's not how DMD 
passes them. On some platforms it matches how a struct is passed, 
on some it doesn't.
