From what I can see of your implementation, if a user wants to invoke Implementation::foo, they will need to include Implementation.h, which effectively negates the benefit of pimpl in the first place.
I really don't understand this, sorry. First, is a method a function/variable/both? Also, could you show the above using code instead of words? That's easier to read I think.
I'd call what you've provided a "Pimpl *Holder*", and not a Generic Pimpl (which I don't think can be implemented anyway).
I certainly do not agree. This is a generic pimpl implementation. Regards, Asger Mangaard
