At risk of sounding a complete wally, I have completely failed to understand why the second version is any way preferrable to the first.
Why would you want to do this?

Are you asking why you would you use a boost::ptr_map over a std::map? I believe it's so the container takes ownership of the pointed to objects. http://www.boost.org/doc/libs/1_35_0/libs/ptr_container/doc/ptr_container.ht... contains this line: "For each of the standard containers there is a pointer container equivalent that takes ownership of the objects in an exception safe manner. In this respect the library is intended to solve the so-called polymorphic class problem." Regards, Pete
