That makes a lot more sense. What confused me is this from Dave
Abrahams in a message from Oct 07, I guess he got them mixed up.
If the is not pre-incremented for you, then
boost::python::handle<> h((PyObject*)callbackID));
return boost::python::object o(h);
would be correct. Otherwise, you need
boost::python::handle<>
h(boost::python::borrowed((PyObject*)callbackID)));
return boost::python::object o(h);
btw, I notice that object(borrowed(ptr)) compiles and runs without
error. Is handle<>(...) superfluous when using borrowed?
