Comment(by kondo@…):

 Now, I have understood your policy.
 Serializing the reference data member is asymmetric. And we should write
 such code.
 But my patch helps hide the such code.

 Now, I think to prepare below cast in my code.

 {{{
 #!cpp
 template <typename T>
 T* const& reference_serialize_cast(T* const& t)
 {
     return t;
 }
 }}}

 {{{
 #!cpp
     ar << boost::serialization::make_nvp("ref_",
 reference_serialize_cast(&p->ref_));
 }}}

 By the way,
 >The reason that we trap a attempt to serialize a non-const is described
 >in the rationale section of the documentation

 means
 http://www.boost.org/doc/libs/1_42_0/libs/serialization/doc/rationale.html

 ?

 or you mean
 http://www.boost.org/doc/libs/1_42_0/libs/serialization/doc/serialization.html#references

 ?
