I can trull

troll.cpp

#include <cmath>
#include <algorithm>
#include <iostream>
#include <tuple>
#include <vector>

int
main()
{
    using namespace std;
    vector<tuple<int, int>> data;
    size_t i = 0;
    generate_n(back_inserter(data),
               pow(4, 11),
               [&i]() { ++i; return make_tuple(i, i); });
}

Wacky. C++11?
