Short query about a specific feature I am interested in.
Will your library enable the following usecase:

struct foo
    template <typename Sig>
    struct result;

    template <typename This, typename A0, typename A1>
    struct result<This(A0, A1)>
        typedef A0;

struct bar
    template <typename A0, typename A1>
    struct result<A0, A1>
        typedef A0;

has_old_result<foo, A1, A2>::type // evaluates to false
has_old_result<bar, A1, A2>::type // evaluates to true

also supporting "variadic" result_of protocol detection.
I failed to come up with a generic solution to that particular problem. Would be
awesome if you solved it :)
