Hmm. Do you really need access to the deleter, or only information about the
deleter type used? Or do you actually need an answer to the question "did I
create this shared_ptr?"
BTW, introspection isn't currently part of shared_ptr because whenever I
encounter a need for yet another shared_ptr feature, I always try _very
hard_ to solve the problem using only the existing public interface. This
unofficial filter has always worked well so far. :-) (And when I failed to
apply it - shared_from_this - it was a mistake.)
Have you considered keeping a std::set< weak_ptr<> > to track shared_ptr
instances created by boost.python? (Shot in the dark, don't yell at me if I
missed the point.)
