[C++-sig] class_<>::add_property() on CVS-HEAD

[Jonathan Brandmeyer]

The following example demonstrates a method of using add_property that
works with Boost.Python 1.30 but not CVS-HEAD (from sourceforge CVS). 
The example posted is somewhat useless as-is, but demonstrates something
that I started using for properties with non-trivial accessors.

Is there a replacement for this functionality?

Thanks,
Jonathan Brandmeyer

#include <boost/python.hpp>

namespace test {

// Hmm.  return_internal_reference<>() wants to wrap a real class.
class ret_type
{
 public:
	double i;
};

class crash_me
{
	private:
		ret_type i;
	public:
		ret_type& get_i() { return i; }
};

}

BOOST_PYTHON_MODULE( crash_test)
{
	using namespace boost::python;
	
	class_< test::ret_type>( "ret_type")
		.def_readwrite( "i", &test::ret_type::i)
		;
	
	class_< test::crash_me> crash_me_wrapper( "crash_me");
	
	crash_me_wrapper
		.def( "get_i", &test::crash_me::get_i , return_internal_reference<>())
		;
	
	// The following works under Boost 1.30, but not CVS-HEAD 
	// (sourceforge repository).
	crash_me_wrapper.add_property( "i", crash_me_wrapper.attr("get_i"));
}
