Is it possible to declare two variables of different types in a for loop?
...ith the std::string, if you want to name a type. For example:
auto [vec, i32] = std::tuple{std::vector<int>{3, 4, 5}, std::int32_t{12}}
A specific application of this is iterating over a map, getting the key and value,
std::unordered_map<K, V> m = { /*...*/ };
