Easy fix: use functors.
obj.func(); would actually do
/* 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;
auto operator(T& t) -> decltype(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?
