There is a more simple solution that doesn't requires a macro.
The expansion of the ...Ts in the string array is perfectly legal and simple.

template<typename ... Ts, typename F>
void enumerate_types (F&& f)
{
    std::string myTypes[] = {typeid(Ts).name()...}; // Here is the trick
    for(auto&& s : myTypes)
    {
        std::forward<F>(f)(s);
    }
}

int main()
{
    enumerate_types<int,bool,char,std::string>(
        std::move([&i](std::string& s)
                         { std::cout << std::to_string(i++) + s + '\n'; })
        );
}
