Easy fix: use functors.

obj.func(); would actually do

struct anonymous_1
     /* some compile-time reflection info here */
     typedef boost::mpl::vector_c<char, 'f', 'u', 'n', 'c'> name;
     static const bool function = true;
     typedef boost::mpl::vector<> args;

     template<typename T>
     auto operator(T& t) -> decltype(t.func())
         return t.func()


I think this would allow, for example, to directly call the member
functions of the underlying object in boost.variant.
Could someone confirm that?
