When is it possible to elide types of temporaries passed into a variadic function template? Overload resolution doesn't seem to work. Consider this:

#include <vector>

struct option
{
    std::vector<int> to_wait;
    std::vector<int> to_set;
};


namespace fsm
{
    template <typename... Ts>
    void generic_wait(Ts... Args) {
        std::array<option, sizeof...(Ts)> hello = {{Args...}};
    }
}


int main()
{
    fsm::generic_wait(option{{2}, {3}}); // <-- This compiles
    // fsm::generic_wait({{2}, {3}}); // <-- This I would like to compile
}

This compiles only when I directly specify the temporary type. If I leave it off it stops working (C++11). Can I do something to make it work?
