Is there a way to use the mpl to determine if an object can be converted to some parent / child class? That is, if A derives from B, can I say something like "mpl::is_convertible_to::value" ?

See Boost.TypeTraits boost::is_base_and_Derived::value or more simply, boost::is_convertible::value MPL metafunctions are of course interoperable with the type traits. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com The Astoria Seminar ==> http://www.astoriaseminar.com
