Personally, I don't need argument policies much.  The one I do need is:

typedef boost::mt19937 rng_t;
  class_<WrappedClass> (python_typename, desc,
			python::init<rng_t&, double>((python::arg("rng"),python::arg("var")),
						     "__init__(r,var)\n"
						     "Construct a normal deviate generator\n"
						     "@param r: Mersenne Twister\n"
						     "@type r: L{rng}\n"
						     "@param var: variance\n"
						     "@type var: float\n"
						     )
			[python::with_custodian_and_ward<1,2>()])

Here, rng_t is boost::mersenne_twister.  The wrapped object needs to hold a 
reference to a rng_t object, so we need "with_custodian_and_ward".
