  Version:  Boost 1.37.0  |    Severity:  Problem

 See http://mail.python.org/pipermail/cplusplus-

 sig/2007-February/011651.html for code that solves this. (the boostPatch
 namespace contents)

 I couldn't find anything on Boost.Python in the release notes for 1.38 or
 1.39, so I assume it's still in there.

 Also, for those who need this before it's included in
 boost::python::class_, a better use of the functions (than the typedeffing
 in the post above) is:

 {{{
 #!cpp
 template<class T, class B, class X, class Y>
 class myclass : boost::python::class_<T, B, X, Y>
 {
 public:
    template<class Constructor>
    myclass(const char* name, const Constructor& t) :
 boost::python::class_<T, B, X, Y>(name, t)
    {
       boostPatch::register_intrusive_ptr_from_python_and_casts( (T *)0,
 metadata::bases() );
    }
 };
 }}}
