While implementing a compressed_tuple class for some project I'm working on, I ran into the following issue: I can't seem to pass instances of this type to std::apply, even though this should be po...

I am trying to create a generic class that takes a pack of types, stores them in a tuple, and can apply a function over them. What I tried so far is the following: #include <tuple> struct ...

Consider possible implementation of std::apply: namespace detail { template <class F, class Tuple, std::size_t... I> constexpr decltype(auto) apply_impl(F &&f, Tuple &&t, std...

I tried code below in Wandbox: #include <array> #include <iostream> #include <tuple> #include <typeinfo> #include <functional> #include <utility> int main() {...

Is it possible to apply a variadic function to a tuple with std::apply? For example, the following code works fine with GCC 6.2.1: void print_t(std::string i, std::string j) { std::cout <<...
