I've read all these details and really found nothing new. What I'm actually saying is that inserting a dummy entry in instances and vtable, we make free for use our objects in the languages who uses such layout with variations. We do not leave them free to interface directly via they vtable. We create dispatchers and let a Pascal class with virtual methods just work. We can create Pascal unit compatible with Delphi and FPC (probably using a conditional directive to insert or not a dummy variable, but I'm waiting for a Delphi guy who wants to test), compatible with different C++ compilers, compatible with C.
