770	static assert for boost::python::make_constructor	jfalk	david_abrahams	"{{{
You get a static assertion when using
boost::python::make_constructor together
with the call policy
return_value_policy<manage_new_object>()

Test case:
=====================================================
#include <boost/python.hpp>

namespace Test {
  using namespace boost::python;

  class Foo {
  };

  Foo *fooCreator() { return new Foo(); }

  BOOST_PYTHON_MODULE(Test)
  {
    class_<Foo>(""Foo"")
      .def(""__init__"", make_constructor(fooCreator,
return_value_policy<manage_new_object>()));
  }

} /* namespace Test */

Failure:
=====================================================
