Say I have a struct D that derives from B, like: struct B { int i1; } struct D : B { int i2; } I can adapt B to be a Fusion sequence with: BOOST_FUSION_ADAPT_STRUCT(B, (int, i1)) Now I want to adapt D. Do I have to enumerate B's members again, or is there a way to express the inheritance relationship so that it Just Works? -- Eric Niebler Boost Consulting www.boost-consulting.com
