Is there a way to implement std::apply in c++11?
I have a std::tuple<Args...> myTuple and a std::function<void(const Args&...)> myFunction
How can I invoke myFunction and pass it the contents of myTuple as arguments in C++11?

1the possible implementation [here](https://en.cppreference.com/w/cpp/utility/apply) is a good start – 463035818_is_not_an_ai May 19 '21 at 20:56
