turns out structured bindings work in ranged for loops!

sb_in_range_for.cpp

#include <map>
#include <iostream>


int main() {
    std::map<int,int> pairs;
    pairs[0] = 1;
    pairs[1] = 5;
    pairs[2] = 4;
    pairs[3] = 3;
    pairs[4] = 2;
    for(auto&& [k,v]: pairs) {
        std::cout << k << " => " << v << std::endl;
    }
    return 0;
}
