[Boost-users] [mpl] apply is_base_and_derived to class template and deduce types

I have a base class template "template struct base {};" and a derived class "derived" that publicly derives from several instantiations from the base class template. Given a type "T1", is it possible to decide if the class "derived" is derived from a base "base" and deduce the unknown type "X"?
