Ok, Another hack:
iInterface x;
void** y = cast(void**)&x;
*y = malloc(iInterface.sizeof);
x.__vptr = cast(immutable(void*)*)(*ptr);
x.func();
works.
x is the object of type iInterface. It has no object associated
with it, basically create one using malloc and set it's vtable.
this avoids the need to create the class.
What happens when you declare an interface that extends from
IUnknown (and not extern(C++)), then cast the pointer returned
from the COM API? It should just work without needing to muck
around with the vtable.
