Yes I do know how the DLL boundary issue is solve ;-) My point is the
reference counting... What is being suggested, by you and others, is to
have a reference counted pointer with deep copy semantics implemented as
copy on write for efficiency. And in my opinion at that point you are
looking at the territory of shared_ptr/weak_ptr, and hence outside of
the intended scope of the pimpl_ptr submission.
