[C++-sig] wrapper and shared_ptr - how to combine?

[Leonard Ritter]

yes, that's what i want. what details do you need? i mean, the problem
posted is quite generic. i want to pass shared_ptr's of abstract classes
with overridable methods back and forth from c++ to python and back. is this
supposed to work, if yes, how?
